The COVID-19 epidemic requiring social distancing through its lockdown measures forced a sudden and total transition from in person to videoconferencing mode of treatment provision, irrespective of the preference of the therapist or client. Routine Outcome Monitoring (ROM) data allowed the comparison of three groups of treatment delivery: (1) treatments that were largely or completely performed in person, (2) treatments that started in person but suddenly switched to treatment via videoconferencing due to the corona measures, and (3) treatments that were performed entirely with video conferencing. The research question in this study is: How does treatment conducted (partially) through videoconferencing compare to in person therapy in effectiveness? It was hypothesized that full in person treatment would be more effective than (partial) videoconferencing treatment. The participants in this research were patients receiving treatment at Sinai Center, a Mental Healthcare Clinic in The Netherlands, specialized in the treatment of PTSD. The patients who were included in this study were predominantly diagnosed with PTSD and had completed their treatment in the years 2018 till 2021. ROM data were used to analyse the pre- and post-test scores of the three cohorts with repeated measures ANOVA in a two (time) by three (conditions) factorial design. Also, the proportions of recovered, improved, unchanged, and deteriorated patients were compared among the three cohorts with a chi-square test. Contrary to what was hypothesized, the results showed that there was no significant difference between the three treatment groups in outcome of therapy. Some limitations of the study may have influenced the results; incomplete background information of the patients to account for in the analyses, lack of a disorder specific questionnaire to measure outcome, the effects of the pandemic and lockdown on the patients.Show less

Linking test scores to T scores as a common metric might be a solution. Item response theory (IRT) is the preferred way to estimate T-scores. However, required software and a large dataset is needed for that. In this thesis, two methods were used to arrive at a common metric for often used questionnaires and their subversions: the BSI, BSI-18, the DASS-42 and the DASS-21. As one method, we used an IRT approach to estimate theta-based T-scores, leading to crosswalk tables. For the second approach, conversion formulas were estimated for raw scores to calculated T-scores based on the best-fitting regression equation between the raw scores and the previously estimated theta-based T-scores. Crosswalk tables and conversion formulas are both alternative ways to link individual scores to a common metric. It was investigated if conversion formulas are valid by comparing calculated T-scores with theta-based T-scores. The agreement between calculated T-scores and theta-based T-scores were high for all questionnaires except the DASS-42. The agreement was also lower at the extreme ends of the questionnaires (T= < 50 and T= >75). All in all, conversion formulas seem to be a good alternative for estimating a common metric. Offering different options to calculate common metrics can help in improving the communication between professionals in the clinical field. Increased involvement and better communication in ROM is able to increase the quality of mental health care.Show less
