Design A Research Paper

INTRODUCTION
Background

This article is written in the form of an original-research paper for the journal Sportscience. A few of the requirements for form and content are unique to Sportscience, but most are common to all good scientific journals. You can therefore use this article to help you write a research paper for any journal.

This article also exists in slightly modified form as a template for a Sportscience research article. If you intend to submit a paper to Sportscience, you should download the template from the Information for Authors page at the Sportscience site.

Whether you are submitting your article to Sportscience or to another journal, you should read my guidelines on scientific writing (Hopkins, 1999). Here are the main points from that article:

  • Avoid technical terms.
  • Avoid abbreviations.
  • Use simple sentences.
  • Avoid common errors of punctuation and grammar.
  • Use the first person (I, we) rather than the passive voice.
  • Link your ideas into a sensible sequence without repetitions or discontinuities.
  • Get feedback on your article from colleagues.

The subheadings in this article (Background, Aim, etc.) should make it easier to write your article for Sportscience than for other journals. You will also be less likely to omit important data or important points for discussion. Please follow the instructions for each subheading. Omit or change the subheadings as necessary for a paper in another journal.

Use the first paragraph or two of the Background to explain what is known generally in the area of your study. Cite key references, but do not write an extensive review of literature; instead, direct the reader to a recent review. Then focus in on the problem that your study addresses.

Aim

State the aim in the first sentence of this section. Write a few more sentences if necessary to justify the aim and/or explain your unique approach to realizing the aim. Make it clear to the reader that your aim or your approach is interesting and that your study is therefore valuable.

METHODS
Design

State the design, then justify your choice of this design. Explain the optimum sample size, then justify the size of the sample you studied. Describe any relevant time frame. Use a figure to explain a complex design or a design involving several assays at different times.

Devote a separate paragraph to a description of the experimental and control treatments (e.g., drug, diet, training) in an experimental study.

Subjects

Explain how the subjects were recruited, then list means and standard deviations of the relevant demographics (age, weight, height) plus any other relevant characteristics (recent best performances, recent training). Show ranges of characteristics only if there are unusually distant outliers in the sample. If possible, report recent best competitive performances of athletes as a percent of the world record, to make it clear what caliber of athlete the outcome of your study can be generalized to.

Show all the above characteristics for any major subgroups of subjects (e.g., males and females, non-athletes and athletes). Include the number of subjects in each subgroup. Use a table like this (tables for other journals have similar formats):

Table 1: Characteristics of the subjectsa.

age (y)

23 ± 4

weight (kg)

etc.

etc.

etc.

  

  

Data are means ± standard deviations.
aPut any footnotes here. Note that the caption and footnotes are in cells of the table.

Measures

List the measures (variables) you used and explain why you chose them, as shown below. Then describe the assay for each under its own sub-subheading. Give an outline of established procedures and refer the reader to previous published accounts for details; for new procedures show enough detail to allow the reader to reproduce the procedures successfully.

Dependent (outcome) variables: list them. Explain why you chose them.

Independent (predictor) variables: list them. Explain why you chose them. For repeated-measures designs omit the obvious treatment variable, but include numeric and nominal variables you have analyzed as covariates.

Mechanism variables: list them. These are variables in repeated-measures designs that you have assayed to try to explain the effect of the treatment. Explain why you chose them.

Measure1

Describe the assay for the first measure under a sub-subheading, as shown here. You may wish to group some measures under one sub-subheading, such as Training, Anthropometric, or Environmental Measures.

Measure2

Describe the assay for the second measure under a sub-subheading, as shown here, and so on. When mentioning a piece of equipment, you must state the model, the manufacturer, and the city and country of origin. Include relevant information on sampling or digitizing rates and data processing that led to the measure.

Analyses

Name the statistical package or program you used. Describe the statistical procedures. Finish this section with this paragraph, or something similar:

We have used means and standard deviations to represent the average and typical spread of values of variables. We have shown the precision of our estimates of outcome statistics as 95% confidence limits (which define the likely range of the true value in the population from which we drew our sample). The p values shown represent the probability of a more extreme absolute value than the observed value of the effect if the true value of the effect was zero or null. Statistically significant effects are those for which the zero or null value of the effect lies outside the 95% confidence interval (i.e., p < 0.05).

RESULTS AND DISCUSSION

Most journals have separate Results and Discussion sections. I believe this separation makes research articles more difficult to write and read.

Technicalities

How close to reality were your measurements? In a repeated-measures study, how reproducible were the dependent variables? How do the answers to these questions impact your findings? Address such questions about the validity and reliability of your measures here. You can also report any ancillary methodological findings. Use sub-subheadings if you wish.

Outcomes

Summarize the spread of values between subjects with the standard deviation, never with the standard error of the mean. Show the precision of your estimates of outcomes with confidence limits. Try not to mention p values, statistical significance, null hypotheses, type I errors, and type II errors.

State each result and discuss it immediately. Interpret the magnitude of each outcome in a qualitative way, using both your experience of the magnitudes that matter in this area of human endeavor and also any published scales of magnitudes (e.g., Cohen, 1988; Hopkins, 1998). You must interpret the observed effects and the 95% confidence limits. For example, you might have to say that you observed a moderate effect, but that the true value of the effect could be anything between trivial and very strong.

If it is more convenient to show p values than confidence limits, show the exact p value to one significant digit (for p < 0.1) or two decimal places (for p > 0.10). Do not use p < 0.05 or p > 0.05. Examples: p = 0.03; p = 0.007; p = 0.09; p = 0.74. Do not give values of test statistics (F, t, etc.).

Show data in figures rather than in tables or in text. See below for examples (Figures 1-4). Avoid repetition of data in figures, tables and text. For Sportscience articles, follow the instructions in the template on how to create figures. Paste figures and tables into the document after the paragraph where you first refer to them (other journals: tables and figures go at the end of the manuscript).

Data are means. Bars are standard deviations (shown only for Groups B and C).
aUse letters to label footnotes, if necessary.

Least-squares lines are shown for each variable.

Figure 3: Informative title for a bar graph.

Data are means. Bars are standard deviations.

Figure 4: Informative title for an outcomes figure.

Data are means. Bars are 95% confidence intervals.

Conclusions

Do your findings apply to people in the real world if they have characteristics and behaviors different from the people in your sample? Bring together the outcomes and any technicalities in a statement that addresses this question about the generalizability of your findings to the population of subjects from which you drew your sample. Then speculate about the applicability to other populations, such as athletes of a different caliber, athletes from other sports, and non-athletes. Finish with specific justified suggestions for future research projects rather than a non-specific call for more research.

The Effects of a Supported Employment Program on Psychosocial Indicators

for Persons with Severe Mental Illness

William M.K. Trochim

Cornell University

Running Head: SUPPORTED EMPLOYMENT


Abstract

This paper describes the psychosocial effects of a program of supported employment (SE) for persons with severe mental illness. The SE program involves extended individualized supported employment for clients through a Mobile Job Support Worker (MJSW) who maintains contact with the client after job placement and supports the client in a variety of ways. A 50% simple random sample was taken of all persons who entered the Thresholds Agency between 3/1/93 and 2/28/95 and who met study criteria. The resulting 484 cases were randomly assigned to either the SE condition (treatment group) or the usual protocol (control group) which consisted of life skills training and employment in an in-house sheltered workshop setting. All participants were measured at intake and at 3 months after beginning employment, on two measures of psychological functioning (the BPRS and GAS) and two measures of self esteem (RSE and ESE). Significant treatment effects were found on all four measures, but they were in the opposite direction from what was hypothesized. Instead of functioning better and having more self esteem, persons in SE had lower functioning levels and lower self esteem. The most likely explanation is that people who work in low-paying service jobs in real world settings generally do not like them and experience significant job stress, whether they have severe mental illness or not. The implications for theory in psychosocial rehabilitation are considered.


The Effects of a Supported Employment Program on Psychosocial Indicators for Persons with Severe Mental Illness

Over the past quarter century a shift has occurred from traditional institution-based models of care for persons with severe mental illness (SMI) to more individualized community-based treatments. Along with this, there has been a significant shift in thought about the potential for persons with SMI to be "rehabilitated" toward lifestyles that more closely approximate those of persons without such illness. A central issue is the ability of a person to hold a regular full-time job for a sustained period of time. There have been several attempts to develop novel and radical models for program interventions designed to assist persons with SMI to sustain full-time employment while living in the community. The most promising of these have emerged from the tradition of psychiatric rehabilitation with its emphases on individual consumer goal setting, skills training, job preparation and employment support (Cook, Jonikas and Solomon, 1992). These are relatively new and field evaluations are rare or have only recently been initiated (Cook and Razzano, 1992; Cook, 1992). Most of the early attempts to evaluate such programs have naturally focused almost exclusively on employment outcomes. However, theory suggests that sustained employment and living in the community may have important therapeutic benefits in addition to the obvious economic ones. To date, there have been no formal studies of the effects of psychiatric rehabilitation programs on key illness-related outcomes. To address this issue, this study seeks to examine the effects of a new program of supported employment on psychosocial outcomes for persons with SMI.

Over the past several decades, the theory of vocational rehabilitation has experienced two major stages of evolution. Original models of vocational rehabilitation were based on the idea of sheltered workshop employment. Clients were paid a piece rate and worked only with other individuals who were disabled. Sheltered workshops tended to be "end points" for persons with severe and profound mental retardation since few ever moved from sheltered to competitive employment (Woest, Klein & Atkins, 1986). Controlled studies of sheltered workshop performance of persons with mental illness suggested only minimal success (Griffiths, 1974) and other research indicated that persons with mental illness earned lower wages, presented more behavior problems, and showed poorer workshop attendance than workers with other disabilities (Whitehead, 1977; Ciardiello, 1981).

In the 1980s, a new model of services called Supported Employment (SE) was proposed as less expensive and more normalizing for persons undergoing rehabilitation (Wehman, 1985). The SE model emphasizes first locating a job in an integrated setting for minimum wage or above, and then placing the person on the job and providing the training and support services needed to remain employed (Wehman, 1985). Services such as individualized job development, one-on-one job coaching, advocacy with co-workers and employers, and "fading" support were found to be effective in maintaining employment for individuals with severe and profound mental retardation (Revell, Wehman & Arnold, 1984). The idea that this model could be generalized to persons with all types of severe disabilities, including severe mental illness, became commonly accepted (Chadsey-Rusch & Rusch, 1986).

One of the more notable SE programs was developed at Thresholds, the site for the present study, which created a new staff position called the mobile job support worker (MJSW) and removed the common six month time limit for many placements. MJSWs provide ongoing, mobile support and intervention at or near the work site, even for jobs with high degrees of independence (Cook & Hoffschmidt, 1993). Time limits for many placements were removed so that clients could stay on as permanent employees if they and their employers wished. The suspension of time limits on job placements, along with MJSW support, became the basis of SE services delivered at Thresholds.

There are two key psychosocial outcome constructs of interest in this study. The first is the overall psychological functioning of the person with SMI. This would include the specification of severity of cognitive and affective symptomotology as well as the overall level of psychological functioning. The second is the level of self-reported self esteem of the person. This was measured both generally and with specific reference to employment.

The key hypothesis of this study is:

HO: A program of supported employment will result in either no change or negative effects on psychological functioning and self esteem.

which will be tested against the alternative:

HA: A program of supported employment will lead to positive effects on psychological functioning and self esteem.

Method

Sample

The population of interest for this study is all adults with SMI residing in the U.S. in the early 1990s. The population that is accessible to this study consists of all persons who were clients of the Thresholds Agency in Chicago, Illinois between the dates of March 1, 1993 and February 28, 1995 who met the following criteria: 1) a history of severe mental illness (e.g., either schizophrenia, severe depression or manic-depression); 2) a willingness to achieve paid employment; 3) their primary diagnosis must not include chronic alcoholism or hard drug use; and 4) they must be 18 years of age or older. The sampling frame was obtained from records of the agency. Because of the large number of clients who pass through the agency each year (e.g., approximately 500 who meet the criteria) a simple random sample of 50% was chosen for inclusion in the study. This resulted in a sample size of 484 persons over the two-year course of the study.

On average, study participants were 30 years old and high school graduates (average education level = 13 years). The majority of participants (70%) were male. Most had never married (85%), few (2%) were currently married, and the remainder had been formerly married (13%). Just over half (51%) are African American, with the remainder Caucasian (43%) or other minority groups (6%). In terms of illness history, the members in the sample averaged 4 prior psychiatric hospitalizations and spent a lifetime average of 9 months as patients in psychiatric hospitals. The primary diagnoses were schizophrenia (42%) and severe chronic depression (37%). Participants had spent an average of almost two and one-half years (29 months) at the longest job they ever held.

While the study sample cannot be considered representative of the original population of interest, generalizability was not a primary goal -- the major purpose of this study was to determine whether a specific SE program could work in an accessible context. Any effects of SE evident in this study can be generalized to urban psychiatric agencies that are similar to Thresholds, have a similar clientele, and implement a similar program.

Measures

All but one of the measures used in this study are well-known instruments in the research literature on psychosocial functioning. All of the instruments were administered as part of a structured interview that an evaluation social worker had with study participants at regular intervals.

Two measures of psychological functioning were used. The Brief Psychiatric Rating Scale (BPRS)(Overall and Gorham, 1962) is an 18-item scale that measures perceived severity of symptoms ranging from "somatic concern" and "anxiety" to "depressive mood" and "disorientation." Ratings are given on a 0-to-6 Likert-type response scale where 0="not present" and 6="extremely severe" and the scale score is simply the sum of the 18 items. The Global Assessment Scale (GAS)(Endicott et al, 1976) is a single 1-to-100 rating on a scale where each ten-point increment has a detailed description of functioning (higher scores indicate better functioning). For instance, one would give a rating between 91-100 if the person showed "no symptoms, superior functioning..." and a value between 1-10 if the person "needs constant supervision..."

Two measures of self esteem were used. The first is the Rosenberg Self Esteem (RSE) Scale (Rosenberg, 1965), a 10-item scale rated on a 6-point response format where 1="strongly disagree" and 6="strongly agree" and there is no neutral point. The total score is simply the sum across the ten items, with five of the items being reversals. The second measure was developed explicitly for this study and was designed to measure the Employment Self Esteem (ESE) of a person with SMI. This is a 10-item scale that uses a 4-point response format where 1="strongly disagree" and 4="strongly agree" and there is no neutral point. The final ten items were selected from a pool of 97 original candidate items, based upon high item-total score correlations and a judgment of face validity by a panel of three psychologists. This instrument was deliberately kept simple -- a shorter response scale and no reversal items -- because of the difficulties associated with measuring a population with SMI. The entire instrument is provided in Appendix A.

All four of the measures evidenced strong reliability and validity. Internal consistency reliability estimates using Cronbach's alpha ranged from .76 for ESE to .88 for SE. Test-retest reliabilities were nearly as high, ranging from .72 for ESE to .83 for the BPRS. Convergent validity was evidenced by the correlations within construct. For the two psychological functioning scales the correlation was .68 while for the self esteem measures it was somewhat lower at .57. Discriminant validity was examined by looking at the cross-construct correlations which ranged from .18 (BPRS-ESE) to .41 (GAS-SE).

Design

A pretest-posttest two-group randomized experimental design was used in this study. In notational form, the design can be depicted as:

R O X O

R O O

where:

R = the groups were randomly assigned

O = the four measures (i.e., BPRS, GAS, RSE, and ESE)

X = supported employment

The comparison group received the standard Thresholds protocol which emphasized in-house training in life skills and employment in an in-house sheltered workshop. All participants were measured at intake (pretest) and at three months after intake (posttest).

This type of randomized experimental design is generally strong in internal validity. It rules out threats of history, maturation, testing, instrumentation, mortality and selection interactions. Its primary weaknesses are in the potential for treatment-related mortality (i.e., a type of selection-mortality) and for problems that result from the reactions of participants and administrators to knowledge of the varying experimental conditions. In this study, the drop-out rate was 4% (N=9) for the control group and 5% (N=13) in the treatment group. Because these rates are low and are approximately equal in each group, it is not plausible that there is differential mortality. There is a possibility that there were some deleterious effects due to participant knowledge of the other group's existence (e.g., compensatory rivalry, resentful demoralization). Staff were debriefed at several points throughout the study and were explicitly asked about such issues. There were no reports of any apparent negative feelings from the participants in this regard. Nor is it plausible that staff might have equalized conditions between the two groups. Staff were given extensive training and were monitored throughout the course of the study. Overall, this study can be considered strong with respect to internal validity.

Procedure

Between 3/1/93 and 2/28/95 each person admitted to Thresholds who met the study inclusion criteria was immediately assigned a random number that gave them a 50/50 chance of being selected into the study sample. For those selected, the purpose of the study was explained, including the nature of the two treatments, and the need for and use of random assignment. Participants were assured confidentiality and were given an opportunity to decline to participate in the study. Only 7 people (out of 491) refused to participate. At intake, each selected sample member was assigned a random number giving them a 50/50 chance of being assigned to either the Supported Employment condition or the standard in-agency sheltered workshop. In addition, all study participants were given the four measures at intake.

All participants spent the initial two weeks in the program in training and orientation. This consisted of life skill training (e.g., handling money, getting around, cooking and nutrition) and job preparation (employee roles, coping strategies). At the end of that period, each participant was assigned to a job site -- at the agency sheltered workshop for those in the control condition, and to an outside employer if in the Supported Employment group. Control participants were expected to work full-time at the sheltered workshop for a three-month period, at which point they were posttested and given an opportunity to obtain outside employment (either Supported Employment or not). The Supported Employment participants were each assigned a case worker -- called a Mobile Job Support Worker (MJSW) -- who met with the person at the job site two times per week for an hour each time. The MJSW could provide any support or assistance deemed necessary to help the person cope with job stress, including counseling or working beside the person for short periods of time. In addition, the MJSW was always accessible by cellular telephone, and could be called by the participant or the employer at any time. At the end of three months, each participant was post-tested and given the option of staying with their current job (with or without Supported Employment) or moving to the sheltered workshop.

Results

There were 484 participants in the final sample for this study, 242 in each treatment. There were 9 drop-outs from the control group and 13 from the treatment group, leaving a total of 233 and 229 in each group respectively from whom both pretest and posttest were obtained. Due to unexpected difficulties in coping with job stress, 19 Supported Employment participants had to be transferred into the sheltered workshop prior to the posttest. In all 19 cases, no one was transferred prior to week 6 of employment, and 15 were transferred after week 8. In all analyses, these cases were included with the Supported Employment group (intent-to-treat analysis) yielding treatment effect estimates that are likely to be conservative.

The major results for the four outcome measures are shown in Figure 1.

It is immediately apparent that in all four cases the null hypothesis has to be accepted -- contrary to expectations, Supported Employment cases did significantly worse on all four outcomes than did control participants.

The mean gains, standard deviations, sample sizes and t-values (t-test for differences in average gain) are shown for the four outcome measures in Table 1.

The results in the table confirm the impressions in the figures. Note that all t-values are negative except for the BPRS where high scores indicate greater severity of illness. For all four outcomes, the t-values were statistically significant (p<.05).

Conclusions

The results of this study were clearly contrary to initial expectations. The alternative hypothesis suggested that SE participants would show improved psychological functioning and self esteem after three months of employment. Exactly the reverse happened -- SE participants showed significantly worse psychological functioning and self esteem.

There are two major possible explanations for this outcome pattern. First, it seems reasonable that there might be a delayed positive or "boomerang" effect of employment outside of a sheltered setting. SE cases may have to go through an initial difficult period of adjustment (longer than three months) before positive effects become apparent. This "you have to get worse before you get better" theory is commonly held in other treatment-contexts like drug addiction and alcoholism. But a second explanation seems more plausible -- that people working full-time jobs in real-world settings are almost certainly going to be under greater stress and experience more negative outcomes than those who work in the relatively safe confines of an in-agency sheltered workshop. Put more succinctly, the lesson here might very well be that work is hard. Sheltered workshops are generally very nurturing work environments where virtually all employees share similar illness histories and where expectations about productivity are relatively low. In contrast, getting a job at a local hamburger shop or as a shipping clerk puts the person in contact with co-workers who may not be sympathetic to their histories or forgiving with respect to low productivity. This second explanation seems even more plausible in the wake of informal debriefing sessions held as focus groups with the staff and selected research participants. It was clear in the discussion that SE persons experienced significantly higher job stress levels and more negative consequences. However, most of them also felt that the experience was a good one overall and that even their "normal" co-workers "hated their jobs" most of the time.

One lesson we might take from this study is that much of our contemporary theory in psychiatric rehabilitation is naive at best and, in some cases, may be seriously misleading. Theory led us to believe that outside work was a "good" thing that would naturally lead to "good" outcomes like increased psychological functioning and self esteem. But for most people (SMI or not) work is at best tolerable, especially for the types of low-paying service jobs available to study participants. While people with SMI may not function as well or have high self esteem, we should balance this with the desire they may have to "be like other people" including struggling with the vagaries of life and work that others struggle with.

Future research in this are needs to address the theoretical assumptions about employment outcomes for persons with SMI. It is especially important that attempts to replicate this study also try to measure how SE participants feel about the decision to work, even if traditional outcome indicators suffer. It may very well be that negative outcomes on traditional indicators can be associated with a "positive" impact for the participants and for the society as a whole.
