The rising numbers of young drug abusers in Hong Kong have attracted much concern by the government. Unfortunately, there are few established studies that have been conducted to evaluate the effectiveness of the existing rehabilitation and treatment programs. The dearth of research in this area can compromise the potential for the improvement of current services and hinder the development of new intervention strategies. The present study aimed to help filling in this gap in the literature through the evaluation of Christian Zheng Sheng College, a school-based rehabilitation program. Across a year of observation, we documented the students’ improvements on a range of outcomes (i.e. self-efficacy, school engagement, civic responsibility, perceived social support and religious coping). We also examined whether the perceived quality of natural mentoring relationships established within Zheng Sheng were related to these changes. Across the four waves, the overall population displayed significant linear growths in all measured outcomes apart from civic responsibility and perceived social support. Results also revealed that the perceived closeness with an identified mentor in Zheng Sheng accounted for differential impact toward youth’s self-efficacy, civic responsibility and perceived social support. Implications of the findings were discussed in particular reference to other drug rehabilitation programs in Hong Kong. / published_or_final_version / Clinical Psychology / Master / Master of Social Sciences

Numerous studies have examined stress coping and some extents of wellbeing in adolescents using drugs, however, not many have assessed changes in these constructs in adolescents undergoing drug rehabilitation. The present study aims to (1) examine changes in coping and domains of subjective wellbeing, and (2) explore potential causal relationship between changes in coping and subjective wellbeing in 111 students currently studying at Christian Zheng Sheng College (ZS). The present study was of cross-sequential design, where students completed the same set of relevant questionnaires at baseline, 4 months, 8 months and 12 months later. Latent Growth Modelling (LGM) and cross-lagged regression analyses were conducted to examine changes in these constructs across time and potential causality between the observed changes. Results from the LGMs suggest that students who have stayed longer at ZS had higher baseline in self-perceived success in important domains in life and overall satisfaction with life than those who have stayed for shorter duration of time. Students who have stayed longer at ZS also had more active coping and positive reframing than those who have stayed for shorter duration of time. Results from the cross-lagged regression models suggest that one’s self-perceived success in important areas of life and overall satisfaction with life possibly predicts one’s use of adaptive strategies, for instance, accommodation (i.e., positive reframing and acceptance) and problem solving (i.e., active coping and planning) in coping with stress. Overall, the results from the present study highlighted the potential of enhancing adolescents’ subjective wellbeing in promoting adaptive stress coping in the drug rehabilitation programme. / published_or_final_version / Clinical Psychology / Master / Master of Social Sciences

The main purpose of this study was to examine, in the natural environment, the relative effects of positive reinforcement and response cost as an adjunct to traditional group counseling in the treatment of substance abusers. While these procedures have been repeatedly reported to be effective in controlled settings, little evidence exists that the results generalize to the natural setting. Further, there is a dearth of research which compares contingency contracting to other modalities in the natural setting. Therefore, a second purpose of this research was to compare the effects of contingency contracting as an adjunct to traditional group counseling versus traditional group counseling alone.Subjects for this study were 45 male enlisted soldiers who were diagnosed as alcohol or drug abusers and were enrolled in an Army Community Drug and Alcohol Assistance Center (CDAAC). Of the subjects, 25 were alcohol abusers and 20 were drug abusers. The mean age was 23 years and the median rank was E4. They were randomly assigned to one of the three treatment conditions.The counselors were six paraprofessional military members of the CDAAC staff. They were given five one-hour training sessions by the experimenter on the use of contingency contracting and reinforcement procedures. They were then randomly assigned to the treatment conditions. All subjects received traditional group counseling. Additionally, subjects in Treatment Condition1 received tokens for, carrying out the contingencies of a two-part weekly contract. Subjects in Treatment Condition 2 received the total possible number of tokens at the onset of treatment and forfeited tokens each week if the contingencies of the contract were not met. Tokens were exchanged at the end of treatment for rewards previously negotiated with each subject. Subjectsin Treatment Condition 3 did no contracting and received no tokens.The dependent variables in this study were the subject's level of depression and hostility. These were measured by the Self-Rating Depression Scale and the Buss-Durkee Inventory, respectively. A counterbalanced pretest-posttest design was used. The instruments were administered in a classroom in the CDAAC to all subjects prior to the first group session and again after the sixth session. The posttest instruments were administered in the reverse order from the pretest.The statistical analyses were accomplished using a one-way multivariate analysis of variance (MANOVA). The analysis of the data revealed no statistical differences between contingency contracting with positive reinforcement or contingency contracting with response cost. Further, there were no differences between contingency contracting as an adjunct to traditional group counseling and group counseling alone.The failure to find significant differences between the groups suggests that contingency contracting may not be a viable therapeutic tool in out-patient settings where the counselor does not have control over all potential reinforcers or where the clients may not have a substantial investment in the reinforcement. If the technique is only successful with highly motivated, voluntary clients, it may be no more effective than the contingencies implicit in other counseling relationships. If the effects of in-patient token economies do not generalize to the natural setting and if these procedures require unrealisitic controls when administered in out-patient settings, the previously reported positive results may have little practical value. Further research should be conducted which compares the effects of contingency contracting to other treatment modalities.
