A Longitudinal Analysis of Factors Associated with Therapeutic Alliances

Clinical factors and early life experiences associated with therapeutic alliance development in treatment for depression or binge eating

OBJECTIVE

This study examines childhood and clinical factors theorized to impact therapeutic alliance development over the course of psychotherapy.

METHOD

Raters assessed the therapeutic alliance of 212 client-therapist dyads, participating in two randomized controlled trials of schema therapy and cognitive behavioural therapy for binge eating or major depression, at three time points. Linear mixed models were used to characterize therapeutic alliance development over time and assess the influence of childhood trauma, perceived parental bonding, diagnosis and therapy type on scores.

RESULTS

Participants differed in initial alliance ratings for all subscales but had similar growth trajectories in all but the patient hostility subscale. A diagnosis of bulimia nervosa or binge eating disorder predicted greater initial levels of client distress, client dependency and overall client contribution to a strong therapeutic alliance, compared with a diagnosis of depression. Therapy type, childhood trauma and perceived parental bonds did not predict alliance scores.

CONCLUSION

Findings highlight the potential influence of clinical and personal characteristics on alliance strength and development, with implications for maximizing treatment outcomes through anticipating and responding to these challenges.

Alliance matters: but how much? A systematic review on therapeutic alliance and outcome in patients with anorexia nervosa and bulimia nervosa

PURPOSE

Patients with eating disorders (ED) pose a high-risk group regarding relapse. The understanding of factors contributing to a better outcome is much-needed. Therapeutic alliance (TA) is one important, pantheoretical variable in the treatment process, which has shown to be connected with outcome. This review looks into a possible predictive effect of TA on outcome as well as related variables.

METHODS

A systematic review with pre-determined inclusion criteria following the PRISMA guidelines was conducted for studies published since 2014. Three previous reviews including studies up until 2014 were analyzed for studies matching our inclusion criteria. A total of 26 studies were included.

RESULTS

The results were heterogeneous between different patient groups. Regarding the predictive effect of TA, in adolescent samples, the TA of either the patients or their parents seems to impact outcome as well as completion. For adults, results are mixed, with a tendency to a greater impact of TA for anorexia nervosa (AN) patients, while some samples of adult bulimia nervosa (BN) patients did not find any relation between TA and outcome.

CONCLUSION

The effect of TA on clinical outcome depends on the patient group. TA has a greater impact on adolescents, irrespective of diagnosis, and on adults with AN. The examined studies have different limitations which include small sample sizes and questionable study design. The examination of motivation as a potential influencing factor is recommended.

Measuring therapeutic alliance in children with autism during cognitive behavior therapy

Therapeutic alliance (TA), or the collaborative relationship between a therapist and client, has been shown to be an important component of intervention success. The objective of this study was to examine the psychometric properties of the Therapy Process Observational Coding System-Alliance Scale (TPOCS-A). The sample consisted of 20 children (19 males) ages 8 to 12 years with autism and their parents (15 mothers, 5 fathers), who completed a cognitive-behavioural intervention designed to improve children's emotion regulation skills. Two trained coders rated early, middle, and late parent and child alliance using the TPOCS-A after watching video recorded therapy sessions. Therapist-reported child involvement, alliance, and adherence were also assessed. Psychometric findings revealed that the TPOCS-A is a reliable and valid measure of therapeutic alliance for children with autism. The implications of examining TA in empirically supported treatments for this population are discussed.
