Qualitative Approximations to Causality: Non-Randomizable Factors in Clinical Psychology

Emotion regulation and psychopathology: Investigating differential associations between emotion regulation skills and psychological symptoms using a network approach

OBJECTIVES

Emotion regulation plays an important role in the development and maintenance of psychopathology. However, the question whether specific ER skills are related to specific psychological symptoms has rarely been studied, but has important implications for targeted interventions. This analysis aims to explore potential differential associations between various ER skills and psychological symptoms using a network analysis approach.

METHODS

Routine data from a transdiagnostic clinical sample of 716 patients (460 females, 256 males) from an outpatient clinic for psychotherapy were analysed. Nine ER skills were assessed with the Emotion Regulation Skills Questionnaire, and nine symptom dimension scores were obtained using the Brief Symptom Inventory. A regularized partial correlation network models including ER skills and individual symptom domains were calculated. Bridge expected influence was calculated to estimate the strength of association of each ER skill with psychological symptoms.

RESULTS

Only the following ER skills were most strongly related to psychological symptoms (bridge expected influence): Tolerance, Confrontation and Modification. All other ER skills were indirectly connected to symptom severity through these four skills. The strongest direct edges between ER skills and symptoms were Modification-Depression, Confrontation-Obsession-Compulsion and Tolerance-Interpersonal Sensitivity, which were significantly stronger than the vast majority of other associations between ER skills and psychological symptoms.

CONCLUSIONS

These exploratory findings provide valuable targets for future studies to investigate specific associations between ER skills and psychological symptoms which could help to improve outcome monitoring and efficacy of interventions targeting ER.

Avoidance of causality outside experiments: Hypotheses from cognitive dissonance reduction

The avoidance of causality in the design, analysis and interpretation of non-experimental studies has often been criticised as an untenable scientific stance, because theories are based on causal relations (and not associations) and a rich set of methodological tools for causal analysis has been developed in recent decades. Psychology researchers (n = 106 with complete data) participated in an online study presenting a causal statement about the results of a fictitious paper on the potential effect of drinking clear water for years on the risk of dementia. Two randomised groups of participants were then asked to reflect on the conflict between the goal of approaching a causal answer and the prevailing norm of avoiding doing so. One of the two groups was also instructed to think about possible benefits of addressing causality. Both groups then responded to a list of 19 items about attitudes to causal questions in science. A control group did this without reflecting on conflict or benefits. Free-text assessments were also collected during reflection, giving some indication of how and why causality is avoided. We condense the exploratory findings of this study into five new hypotheses about the how and why, filtered through what can be explained by cognitive dissonance reduction theory. These concern the cost of addressing causality, the variety of ways in which dissonance can be reduced, the need for profound intervention through teaching and social aspects. Predictions are derived from the hypotheses for confirmation trials in future studies and recommendations for teaching causality. Open data are provided for researchers' own analyses.

Causality in psychotherapy research: Towards evidential pluralism

Identifying causal relationships is at the heart of all scientific inquiry, and a means to evidence base practices and to guide policymaking. However, being aware of the complexities of interactions and relationships, scientists and academics are cautious about claiming causality. Researchers applying methods that deviate from the experimental design generally abstain from causal claims, reserving them for designs that adhere to the evidential ideals of empiricism (e.g., RCTs), motivated by the Humean conceptions of causality. Accordingly, results from other designs are ascribed lower explanatory power and scientific status. We discuss the relevance of also other perspectives of causality, such as dispositionalism and the power perspectives of various realist approaches, which emphasize intrinsic properties and contextual variations, as well as an inferentialist/epistemic approach that advocates causal explanations in terms of inferences and linguistic interaction. The discussion will be illustrated by the current situation within psychotherapy research and the APA Policy Statement on Evidence-Based Practice. The distinction between difference-making and causal production will be proposed as a possible means to evaluate the relevance of designs. We conclude that clarifying causal relationships is an ongoing process that requires the use of various designs and methods and advocate a stance of evidential pluralism.

Posttraumatic Stress Symptoms and its Association with Rumination, Thought Suppression and Experiential Avoidance: a Systematic Review and Meta-Analysis

Posttraumatic stress disorder (PTSD) is a severe mental disorder causing high individual and societal costs. The use of maladaptive emotion regulation (ER) strategies has been identified as a potential contributing factor. This meta-analysis aimed to quantify the associations between PTSD symptoms and rumination, thought suppression and experiential avoidance. The systematic literature search resulted in 5574 studies, 75 of which were included in the analysis. From those eligible studies 189 effect sizes were obtained. For symptoms of posttraumatic stress, large effects were found for associations with rumination (r = .52) and experiential avoidance (r = .48), whereas a medium effect size was found for thought suppression (r = .29). With respect to different PTSD symptom clusters, associations ranged between r = .35 and r = .41 for associations with intrusive re-experiencing, between r = .39 and r = .41 for associations with avoidance, between r = .50 and r = .53 for associations with alterations in cognitions and mood and between r = .41 and r = .45 for associations with alterations in arousal and activity. Few available studies provide some evidence that associations might be somewhat reduced but still substantial in longitudinal compared to cross-sectional studies. These findings provide valuable targets for future investigations with the long-term goal of improving targeted interventions for the prevention and treatment of PTSD symptoms.
