How to Evaluate a Tailor-made Social Work Intervention? Some Practice-Based Solutions with Single-Case Designs

PURPOSE

With the increased attention to the principles of evidence-based practice (EBP), social workers are challenged to adapt their daily interventions accordingly when treating clients. They usually work with individual clients, all with their own specificities. Single-Case Experimental Designs (SCEDs) can be used to inform a social worker about the effectiveness of an intervention at the individual client level. In everyday social work practice, however, it is difficult to meet methodological requirements of SCEDs to find causal explanations. A concern is that repeated measurements prior to an intervention are required in most situations. This study aims to provide researchers with alternatives to repeated measurement when using the logic of SCED to apply EBP in their everyday practice.

METHODS

In this study, we reviewed published single-case designs between January 1 and December 31, 2019, on types of SCEDs in the social domain, and how is dealt with baseline conditions.

RESULTS

SCEDs and quasi-experimental alternatives are hardly published in situations when baseline data are not available. Four underused quasi-experimental strategies that can be employed when repeated measurement during baseline is not possible are as follows: retrospective baselines, theoretical inference, multiraters, and triangulation with qualitative data.

DISCUSSION AND CONCLUSION

The suggestions to work with single-case designs with quasi-experimental elements are meant to enable social workers to evaluate their interventions in a way that enhances mere narrative evaluations of the experiences of an intervention.

Application of unified protocol as a transdiagnostic treatment for emotional disorders during COVID-19: An internet-delivered randomized controlled trial

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has been an emotionally challenging time, especially for young adults. It is associated with a substantial increase in the prevalence of mental health problems, negative symptoms, and stressful experiences that compromise well-being. In low-income countries, internet-delivered psychological services could have a remarkable impact on the population’s mental health, given the lack of mental health professionals.

AIM

To investigate the efficacy of internet-delivered cognitive-behavior therapy (CBT)-transdiagnostic intervention for adults with emotional disorders.

METHODS

In this internet-delivered randomized controlled trial, 102 students with an emotional disorder (mean age = 28.20 years, standard deviation = 5.07) were randomly allocated to receive unified protocol (UP) (n = 51) or treatment as the usual intervention. Following a semi-structured clinical interview, participants completed an online survey including the Overall Anxiety Severity and Impairment Scale, Overall Depression Severity and Impairment Scale, Difficulties in Emotion Regulation Scale, Positive and Negative Affect Schedule, and Emotional Style Questionnaire.

RESULTS

The participants showed a high degree of adherence. In total, 78% (n = 40) of the experimental group participants completed the UP treatment. Considering the intention to treat procedure, the results of the analysis of covariance indicated that participants who received UP showed statistically significant changes in depression symptoms [Cohen’s d = -1.50 with 95% confidence interval (CI): -1.90 to -1.10], anxiety (Cohen’s d = -1.06 with 95%CI: -1.48 to -0.65), difficulties with emotion regulation (Cohen’s d = -0.33 with 95%CI: -0.7 to -0.06), positive affect (Cohen's d = 1.27 with 95%CI: 0.85 to 1.68), negative affect (Cohen’s d= -1.04 with 95%CI: -1.46 to -0.63), and healthy emotionality (Cohen’s d = 0.53 with 95%CI: 0.09 to 0.13) compared with the control group.

CONCLUSION

This study’s findings highlight the potential value of transdiagnostic internet-delivered programs for young adults with an emotional disorder during the COVID-19 pandemic, and expand the research examining emotional well-being improvements resulting from CBT-transdiagnostic interventions. The findings suggest that UP, which generally concentrates on reducing negative effects, can increase positive effects.
