A Multiple-Baseline Evaluation of Acceptance and Commitment Therapy Focused on Repetitive Negative Thinking for Comorbid Generalized Anxiety Disorder and Depression.

Repetitive negative thinking (RNT) is a core feature of generalized anxiety disorder (GAD) and depression. Recently, some studies have shown promising results with brief protocols of acceptance and commitment therapy (ACT) focused on RNT in the treatment of emotional disorders in adults. The current study analyzes the effect of an individual, 3-session, RNT-focused ACT protocol in the treatment of severe and comorbid GAD and depression. Six adults meeting criteria for both disorders and showing severe symptoms of at least one of them participated in the study. A delayed multiple-baseline design was implemented. All participants completed a 5-week baseline without showing improvement trends in emotional symptoms (Depression Anxiety and Stress Scale - 21; DASS-21) and pathological worry (Penn State Worry Questionnaire; PSWQ). The ACT protocol was then implemented, and a 3-month follow-up was conducted. Five of the six participants showed clinically significant changes in the DASS-21 and the PSWQ. The standardized mean difference effect sizes for single-case experimental design were very large for emotional symptoms (d = 3.34), pathological worry (d = 4.52), experiential avoidance (d = 3.46), cognitive fusion (d = 3.90), repetitive thinking (d = 4.52), and valued living (d = 0.92 and d = 1.98). No adverse events were observed. Brief, RNT-focused ACT protocols for treating comorbid GAD and depression deserve further empirical tests.

Repetitive negative thinking longitudinally predicts the psychological adjustment of clinical psychology trainees / Pensamiento negativo repetitivo predice el ajuste psicológico de los estudiantes de psicología clínica en práctica

Clinical psychology trainees often experience emotional difficulties during their clinical training. This study aims to examine the predictive ability of repetitive negative thinking (RNT) for emotional symptoms of clinical psychology trainees. A longitudinal study with 236 clinical psychology trainees was conducted. Before beginning clinical practice (T1), participants responded to measures of emotional symptoms, experiential avoidance, general RNT, and RNT focused on the clinical practice. After two months, participants responded to the measures of emotional symptoms. Bayesian regression analyses showed that the measures of emotional symptoms and RNT focused on the clinical practice at T1 predicted emotional symptoms at T2, whereas general experiential avoidance and RNT did not enter the regression models. These results show that RNT focused on the clinical practice longitudinally predicts emotional symptoms of trainees. Interventions aimed at reducing RNT focused on clinical practice might be efficacious to prevent the increase of emotional symptoms in trainees and to enhance learning during the training

Los practicantes de psicología clínica suelen mostrar dificultades emocionales durante su entrenamiento clínico. Este estudio tiene como objetivo analizar la capacidad predictiva del pensamiento negativo repetitivo (PNR) sobre los síntomas emocionales de los estudiantes de psicología clínica en práctica. Se llevó a cabo un estudio longitudinal con 236 practicantes. Antes de comenzar la práctica clínica (T1), los practicantes respondieron a medidas de síntomas emocionales, evitación experiencial, PNR general y PNR centrado en la práctica clínica. Tras dos meses, los participantes respondieron de nuevo a medidas de síntomas emocionales. Los análisis de regresión Bayesianos mostraron que las medidas de síntomas emocionales y PNR centrado en la práctica clínica en el T1 predijeron los síntomas emocionales en el T2, mientras que la evitación experiencial y PNR no entraron en los modelos de regresión. Estos resultados muestran que el PNR centrado en la práctica clínica predice longitudinalmente los síntomas emocionales de los practicantes. Las intervenciones con el objetivo de reducir PNR centrado en la práctica clínica podrían ser eficaces en la prevención del aumento de síntomas emocionales de los practicantes y mejorar el aprendizaje durante el entrenamiento
