Objective
We compared the effects of two brief psychoeducation programs and social skills training on the negative attitudes of mothers with a son who has schizophrenia.
Methods
15 mothers with strong negative feelings towards a sons with schizophrenia were assigned by convenience to participate in one of three brief (5 session) group programs at an outpatient clinic: lecture-based psychoeducation, video-based psychoeducation, or social skills training. Assessments using the Patient Rejection Scale were conducted with the mothers at post-treatment, and 3-, 6-, and 9-months later.
Results
Mothers in the three groups demonstrated significantly different patterns of changes in their negative attitudes following treatment. Whereas the mothers who received the two psychoeducation interventions showed reductions in rejecting attitudes immediately following the program, their scores gradually increased at the subsequent follow-up assessments. In contrast, the mothers in the social skills training group showed reductions in negative attitudes that were sustained across all of the follow-up assessments.
Conclusion
Brief social skills training may be more effective than psychoeducation in reducing negative attitudes of parents who have an offspring with schizophrenia.

Providing care to a loved one with schizophrenia can be a challenging experience, both with respect to the time, expense, and loss of other opportunities associated with caregiving, or objective burden, and emotionally, as relatives must contend with feelings of worry, anxiety, guilt, frustration, and anger in their attempts to cope with a strange and unpredictable illness, or subjective burden.1,2 Although many relatives report gratifications associated with caring for a close persons with severe mental illness,3 strained relationships are common, as shown in research on expressed emotion in families.4 A major factor contributing to distress in caregivers is the severity and disruptiveness of the relative's symptoms and behaviors, such as unpredictable shifts in mood and thinking, bizarre and frightening or embarrassing behavior, failure to follow through on treatment, lack of initiative and involvement in family life, and substance abuse.5,6
Bolstering the coping skills of caregivers for managing disruptive, symptomatic behavior in a loved one has been recommended as one approach to reducing relative distress.6,7 Improved coping skills are a common goal of intermediate or long-term multi-family groups, which usually combine psychoeducation with family support and problem solving delivered over at least several months, if not longer.8-12 Furthermore, some long-term single family interventions for schizophrenia (e.g., nine months or more) combine psychoeducation with skills training approaches in order to improve the coping of family members.13-15
However, shorter-term interventions (e.g., less than 3 months) for family members tend to emphasize psychoeducation about mental illness, with little or no attention to enhancing coping skills.16-19
To our knowledge, no short-term family intervention programs for schizophrenia have attempted to reduce caregiver distress by focusing mainly on skills training rather than providing psychoeducation about the illness. Social skills training techniques have significant potential for reducing caregiver distress as it involves the systematic teaching of new interpersonal skills that can be used immediately by participants to improve their interactions with others,20,21 including family members. This may enable caregivers to begin experiencing the positive effects of more effective communication skills after only a few sessions of training, with the improved communication maintained over the long-term due to its naturally reinforcing effects on reduced interpersonal distress.
The present pilot study was conducted to evaluate the feasibility and potential clinical benefits of providing short-term social skills training to family caregivers aimed at improving their skills for interacting with an offspring with schizophrenia. As teaching family members information about schizophrenia and its treatment is considered the most standard approach to short-term family psychoeducation,7,22,23 we chose to compare the skills training intervention to two didactic approaches to group family psychoeducation: in-person teaching and video-based teaching. We hypothesized that short-term social skills training would lead to more sustained reductions in caregiver distress compared to the two short-term family psychoeducation approaches.
The study took place at an outpatient mental health treatment program affiliated with Dong-A university hospital in Korea. All research methods were approved by the local university Institutional Review Board.
Participants
The subjects were mothers who had a son with schizophrenia receiving outpatient psychiatric treatment at Dong-A university hospital in Korea, and who reported strong, distressing feelings about their relationship with their son. In order to identify mothers with high levels of distress related to their relationship with their son, mothers of sons with schizophrenia living at home completed a revised version of the Patient Rejection Scale.24 This scale includes 11 items (four are reversed scored), each one rated on a three-point scale, corresponding to: 1=never, 2=sometimes, and 3=often, with high scores reflecting more negative, rejecting attitudes towards the family member with mental illness. In order to increase the potential sensitivity of this scale to intervention, the three-point rating scale was changed to a five-point scale, corresponding to: 1=never, 2=seldom, 3=sometimes, 4=often, and 5=constantly. Mothers who scored a 3 or higher on all 11 items (after reversing scores on the four items) were eligible to participate in the study. See Measures section for more information about the Patient Rejection Scale.
Eligible mothers were provided an explanation about the research, which was described as a study intended to compare different approaches to helping family members cope with a close relative who has schizophrenia. After the nature of the interventions were described, and the assessment procedures were completed, interested mothers provided written informed consent to participate in the research. They were then assigned to the next available group they could attend. Different times were established for the family intervention programs, and thus each mother were assigned to the group that was scheduled at the time that could be most readily accommodated into her schedule.
A total of 15 mothers participated in the study. All of the mothers were in their 50s, had graduated high school, and had sons who were in their 20s who had also graduated high school. The baseline demographic and clinical characteristics of the study participants in each of the three treatment groups (see below) are summarized in Table 1. One-way analyses of variance (ANOVAs) were performed to evaluate whether there were any significant differences between the groups. None of these ANOVAs was significant (p>0.1), indicating that the three treatment groups were comparable in these demographic and clinical characteristics.

Treatments
Eligible mothers were assigned to one of three group programs designed to reduce distress and improve coping in relatives of people with schizophrenia: lecture-based (live) family psychoeducation, video-based family psychoeducation, or social skills training. Each program was provided weekly for four weeks, with sessions lasting 90 minutes, and five mothers per group. No further contact occurred between the group participants and each other or the clinician following completion of the group.
Psychoeducation interventions
The lecture-based psychoeducation program began each session with a 60-minute presentation with curriculum based on the Korean translation of Coping with Schizophrenia: A Guide for Families.25 The topics covered included: the prevalence and symptoms of schizophrenia; the principles of treatment (e.g., medication, stress management, social support, rehabilitation); understanding medication non-adherence; dealing with challenging situations such as medication non-adherence, bizarre or threatening behavior, suicidal thinking or behavior, severe negative symptoms, and substance abuse; and other issues related to client functioning, such as friendships, pregnancy, and work. A 30-minute question-and-answer period followed the lecture, in which mothers could ask questions specific to their own experiences, and share with each other effective strategies for handling common challenges. The video-based psychoeducation program included four videos that covered the same topics as the lectures, which were followed by a similar 30-minute question-and-answer period.
Social skills training intervention
The social skills training program was aimed at helping the mothers develop more effective interpersonal skills for coping with common challenging situations with their sons through the application of systematic skills training methods,20 including modeling (demonstrating) effective skills, engaging participants in role plays to practice skills, providing positive and corrective feedback after role plays to reinforce effort and good skills and make suggestions for improvements, additional role play practice, and mutually agreed upon home assignments for the mothers to practice their skills at home. Effective strategies for handling the following problem situations, based on the Coping with Schizophrenia book,25 were taught: violent behavior, medication non-adherence, bizarre or delusional speech, severe negative symptoms, suicidal behavior or ideation, and substance abuse.
The first social skills training group began with an introduction of the leader and group members, and a discussion of common challenging situations experienced by the mothers related to their sons with schizophrenia. Based on this discussion, a problem situation was identified to work on. The leader modeled the skill in one or more role plays, and then enga-ged each mother in several role plays to practice the skill. All role plays were followed by positive feedback and suggestions for improvement. At the end of the session a home assignment was developed for each mother to practice the skill on her own. The next group began with a review of the home assignment, selected role playing of mothers' experiences using the skill over the past week, discussion of the next problem area, and modeling and role playing of skills as in the first session, ending with the development of a home assignment.
Measures
At baseline, client's symptoms were evaluated with the Positive and Negative Syndrome Scale (PANSS),26 a widely used semi-structured interview for assessing the severity of psychiatric symptoms over the past week.
The Patient Rejection Scale,24 modified as previously described, was administered to the mothers at baseline to determine eligibility for the study, again one month later following the completion of each program, and then again 3-, 6-, and 9-months later. The Patient Rejection Scale has good internal reliability, with coefficient α's ranging between 0.71 and 0.83,14,27-29 and good test-retest reliability, with Pearson correlations ranging between 0.72 and 0.92.14,30 In addition, the Patient Rejection Scale has demonstrated convergent validity cross culturally, with research conducted in the U.S.,14 Germany,28,29 Israel,27 and India.30
At the baseline assessment of the present study, coefficient α for the Patient Rejection Scale was 0.56, at the post-treatment assessment it was 0.66, at 3-months post-treatment it was 0.58, at 6-months it was 0.68, and at 9-months post-treatment coefficient α was 0.80. The increase in coefficient α over the different assessments appears to reflect the fact that the study sample was initially selected based on uniformly high ratings on all items on the Patient Rejection Scale (participants score 3 or higher on all items), thereby constraining the range of possible scores and reducing the potential magnitude of the intercorrelations among items, or coefficient α. In the absence of such imposed constraints, there was more variability in the ratings of different items, to the point where the coefficient α for the Patient Rejection Scale was greatest at the follow-up assessment with the greatest amount of variability on that scale. These coefficient α's suggest acceptable levels of internal reliability of the Patient Rejection Scale in this sample.
Statistical analyses
We evaluated differences between the three groups at baseline on participant age, years of education, marital status, and attitude on the Patient Rejection Scale, as well as the age of the son and total symptom severity on the PANSS, by performing one-way ANOVAs, with the three groups as the independent variable.
We used two approaches to evaluate the impact of the three caregiver interventions on changes in the Patient Rejection Scale from baseline to the post-treatment and 3-, 6-, and 9-month follow-up assessments. First, we performed mixed design ANOVAs across all assessments,31 with treatment group assignment as the independent variable. For these analyses, the group by time interaction is a test of whether the three groups differed over time in changes in the Patient Rejection Scale scores. Second, to compare the three treatment groups on the Patient Rejection Scale scores at each assessment following the baseline, we performed a series of one-way ANOVAs at the post-treatment, and 3-, 6-, and 9- month assessments. Significant group effects (p<0.05), indicating differences between the three groups, were followed up by conducting Tukey's Honestly Significantly Different (HSD) tests.
The ANOVAs comparing the three treatment groups at baseline on demographic, clinical, and attitude ratings indicated no significant differences between the groups.
Figure 1 shows the total scores on the Patient Rejection Scale at the five assessments. It can be seen that all three groups showed a reduction in the Patient Rejection Scale from baseline to the post-treatment assessment. However, the two psychoeducation groups gradually increased at the follow-up assessments, whereas the patient rejection ratings for the mothers in the social skills training group remained low.

The mixed design ANOVAs of changes in the Patient Rejection Scale indicated that the main effects for group, F(2, 30)=0.509, NS, and time F(1, 44)=1.155, NS, were not statistically significant (ps>0.10). However, the group by time interaction was significant, F(2, 44)=3.442, p=0.041, indicating significantly different changes over time between the three treatment groups. The ANOVA comparing the three groups at post-treatment indicated no significant differences, F(2, 12)=2.173, NS. The ANOVA for the 3-month assessment was significant, F(2, 12)=4.238, p=0.041, as well as the ANOVAs for 6 months, F(2, 12)=6.568, p=0.012 and 9 months, F(2, 12) =11.960, p=0.001. Tukey HSD tests indicated that at the 3-month assessment mothers in the social skills training program had significantly (p<0.05) lower scores than on the Patient Rejection Scale than mothers in the video program, with mothers in the lecture program not significantly different from either group. For the 6-month and 9-month assessments, the Tukey HSD tests indicated that the mothers in the social skills program had significantly lower scores than those in the lecture or video program, which did not differ.
Mothers who participated in all of the different programs showed major reductions in their negative attitudes towards their sons immediately after completing either of the three treatment programs, with no differences between the live psychoeducation program, the video-based psychoeducation program, or the social skills training program. However, over the next nine months, the mothers in the two psychoeducational programs showed gradual increases in their rejecting attitudes towards their sons, whereas the mothers in the social skills training program did not, with the difference between the groups statistically significant at each follow-up point. Thus, social skills training was more effective than psychoeducation at producing sustained reductions in the negative attitudes of mothers towards a son with schizophrenia.
All three programs were associated with a dramatic reduction in the negative attitudes of the mothers towards their sons. The message of hope contained in the two psychoeducational interventions, combined with social support from the other mothers in the group, may have contributed to these immediate reductions in rejecting attitudes among these participants.10,32 However, social support from other mothers was available to the study participants for only a limited period of time (i.e., a four-week period). It is possible that lack of access to long-term social support over time (e.g., multiple family support groups), in the absence of training more effective and long-lasting interpersonal skills for dealing with challenging situations involving their sons, may have contributed to the waning of beneficial effects on negative attitudes for mothers in the two psychoeducational interventions.
In contrast to the psychoeducation programs, the skills training program had more enduring effects on reducing the mothers' rejecting attitudes towards their son. Social skills training is aimed at teaching individuals more effective interpersonal skills through the systematic application of the principles of social learning theory: modeling, repeated behavioral rehearsal, reinforcement to shape behaviors, homework to generalize newly learned behaviors to real life situations.20 Thus, skills training may have enabled these mothers to develop more effective interpersonal coping strategies for dealing with challenging situations, which they were able to use on their own after the program had ended. These findings suggest that short-term programs aimed at improving coping skills and negative attitudes of family members towards a member with severe mental illness would benefit from the inclusion of skills training aimed at teaching more effective interpersonal behaviors, and should avoid a narrow focus on providing psychoeducation.
Several limitations of this pilot study should be noted. First, the sample size was small, and therefore the findings are in need of replication with a larger number of participants. Second, mothers were not randomized to the different programs. Although the groups did not differ at baseline on any measures, there is a need to more rigorously evaluate the effects of the social skills training program in a randomized controlled trial. Third, the study focused only on mothers and sons, suggesting the need to extend the research to fathers and other family members who may play a caregiving role to relatives with schizophrenia, as well as daughters with schizophrenia. These limitations notwithstanding, this study suggests that time-limited social skills training may have an important role to play in helping distressed caregiving relatives cope more effectively with challenging behaviors in an offspring with schizophrenia, and that more research is warranted on this approach.
