    Psychotherapeutic Process in Adults with Depressive and Anxiety Symptoms Who Report Childhood Maltreatment: A Scoping Review
    (2025) Vaccarezza, Stephanie; Labbé, Nicolás; López, Alberto; Mundt, Adrian P.; Errázuriz, Paula
    Extensive research exists regarding the impact of childhood maltreatment (CM) on depression and anxiety in adulthood. Still, its effect on the psychotherapeutic process, particularly symptomatic change and working alliance, remains unclear. Evaluating studies on the impact of CM on the psychotherapeutic process can help identify research gaps. This study aimed to conduct a scoping review of studies on the psychotherapeutic process in individual psychotherapy of adults with symptoms of depression and anxiety who report CM. The study followed the JBI Scoping Review Methodology. Searches were conducted in October 2022 across eight databases for peer-reviewed articles, books, and gray literature. Eligible studies examined the psychotherapeutic process in individual psychotherapy of adults with depression and/or anxiety who reported CM. A narrative method was employed to analyze and synthesize the studies. A total of 39 studies were included, consisting of 35 scientific articles and four doctoral dissertations. Most were randomized controlled trials evaluating different psychotherapeutic approaches, primarily cognitive-behavioral, interpersonal, and psychodynamic therapies. Patients with CM responded to psychotherapies for anxiety and depression, but showed higher symptom levels at both the beginning and end of treatment, along with delayed responses. A strong working alliance was essential for outcomes across different psychotherapeutic approaches. Psychotherapies for anxiety and depression in patients with CM should focus on building a strong working alliance and consider additional time for treatment responses. Future psychotherapy research on people with CM should report on the processes, including the working alliance. More studies assessing personality, anxiety, therapists’ perspectives, and employing qualitative methodologies are needed

    “What If We Get Sick?”: Spanish Adaptation and Validation of the Fear of Illness and Virus Evaluation Scale in a Non-clinical Sample Exposed to the COVID-19 Pandemic
    (2021) Cottin, Marianne ; Hernández, Cristóbal ; Núñez, Catalina ; Labbé, Nicolás ; Quevedo, Yamil ; Davanzo, Antonella; Alex Behn
    Distinct sources of stress have emerged during the COVID-19 pandemic. Particularly, fear is expected to generate significant psychological burden on individuals and influence on either unsafe behavior that may hinder recovery efforts or virus-mitigating behaviors. However, little is known about the properties of measures to capture them in research and clinical settings. To resolve this gap, we evaluated the psychometric properties of a novel measure of fear of illness and viruses and tested its predictive value for future development of distress. We extracted a random sample of 450 Chilean adult participants from a large cross-sectional survey panel and invited to participate in this intensive longitudinal study for 35 days. Of these, 163 ended up enrolling in the study after the demanding nature of the measurement schedule was clearly explained to them. For this final sample, we calculated different Confirmatory Factor Analyses (CFA) to evaluate the preliminary proposed structure for the instrument. Complementarily, we conducted a content analysis of the items to qualitatively extract its latent structure, which was also subject to empirical test via CFA. Results indicated that the original structure did not fit the data well; however, the new proposed structure based on the content analysis did. Overall, the modified instrument showed good reliability through all subscales both by its internal consistency with Cronbach's alphas ranging from 0.814 to 0.913, and with test-retest correlations ranging from 0.715 to 0.804. Regarding its convergent validity, individuals who scored higher in fears tended to also score higher in depressive and posttraumatic stress symptoms at baseline. Furthermore, higher fears at baseline predicted a higher score in posttraumatic stress symptomatology 7 days later. These results provide evidence for the validity, reliability, and predictive performance of the scale. As the scale is free and multidimensional potentially not circumscribed to COVID-19, it might work as a step toward understanding the psychological impact of current and future pandemics, or further life-threatening health situations of similar characteristics. Limitations, practical implications, and future directions for research are discussed.
