- Objective: Even though the early alliance has been shown to robustly predict posttreatment outcomes, the question whether alliance leads to symptom reduction or symptom reduction leads to a better alliance remains unresolved. To better understand the relation between alliance and symptoms early in therapy, we meta-analyzed the lagged session-by-session within-patient effects of alliance and symptoms from Sessions I to 7. Method: We applied a 2-stage individual participant data meta-analytic approach. Based on the data sets of 17 primary studies from 9 countries that comprised 5,350 participants, we first calculated standardized session-by-session within-patient coefficients. Second, we meta-analyzed these coefficients by using random-effects models to calculate omnibus effects across the studies. Results: In line with previous meta-analyses, we found that early alliance predicted posttreatment outcome. We identified significant reciprocal within-patient effects between alliance and symptoms within the first 7 sessions. Cross-level interactions indicated that higher alliances and lower symptoms positively impacted the relation between alliance and symptoms in the subsequent session. Conclusion: The findings provide empirical evidence that in the early phase of therapy. symptoms and alliance were reciprocally related to one other, often resulting in a positive upward spiral of higher alliance/lower symptoms that predicted higher alliances/lower symptoms in the subsequent sessions. Two-stage individual participant data meta-analyses have the potential to move the field forward by generating and interlinking well-replicable process-based knowledge.

- The study utilized a generalizability theory analysis of adherence and competence ratings to evaluate the number of sessions and patients needed to yield dependable scores at the patient and therapist levels. Independent judges' ratings of supportive expressive therapy (n = 94), cognitive therapy (n = 103), and individual drug counseling (n = 98) were obtained on tapes of sessions from the NIDA Collaborative Cocaine Treatment Study. Generalizability coefficients revealed that, for all three treatments, ratings made on approximately five to 10 sessions per patient are needed to achieve sufficient dependability at the patient level. At the therapist level, four to 14 patients need to be evaluated (depending on the modality), to yield dependable scores. Many studies today use fewer numbers.

Beyond the Blank Screen : Internet-Delivered Psychodynamic Therapy for Adolescent Depression: Evaluating Non-Inferiority, the Role of Emotion Regulation, and Sudden Gains
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Adolescent major depressive disorder (MDD) is a common and debilitating disorder, associated with clinically significant distress and impairment in functioning. A vast array of negative consequences of adolescent MDD have also been found to extend into adulthood. Still, the majority of affected youths do not receive adequate treatment. Internet-delivered interventions address many barriers to treatment, for instance stigma and lack of qualified psychiatric care. However, the most studied internet-delivered treatment, internet-delivered cognitive behavioural therapy (ICBT), leads to clinically meaningful change in somewhat less than 50% of participants. These results indicate the need for treatment alternatives. This thesis consists of three empirical studies examining a newly developed such alternative, internet-delivered psychodynamic treatment (IPDT). Study 1 (n = 272) was a randomised controlled trial, testing whether IPDT was non-inferior to ICBT for depressed adolescents (15–19 years). Results indicated that both treatments were effective, with large within-group effects, and that IPDT was non-inferior to ICBT. No significant differences were noted on primary or secondary outcomes in the intent-to-treat analyses. Study 2 (n = 67) tested emotion regulation as a baseline predictor of rate of change, and whether intra-individual change in emotion regulation was a mechanism of change in IPDT. Results indicated that patients with relatively more severe deficits in emotion regulation had a steeper trajectory towards improvement. Intra-individual changes in emotion regulation also predicted improvements in the subsequent week, indicating that emotion regulation acted as a mechanism of change in IPDT. Study 3 (n = 66) tested whether sudden gains (SGs) and large intersession improvements (LIIs; defined as SGs without demanding symptom stability pre- and post-gain) were associated with superior outcome. LIIs were associated with improved outcome at post-treatment and at follow-up, whilst SGs were not. Overall, the above findings suggest that IPDT is a viable alternative to ICBT for depressed adolescents, that IPDT partly works through increases in emotion regulation and that patients who improve suddenly, between consecutive weeks in IPDT, are more likely to benefit from treatment.
