... Another explanation could be that there might have been greater initial focus on stress perception, which would potentially buffer the stress-reducing effects due to the intervention. This is supported by findings from psychotherapeutic interventions [53,54], in which the hypothesized effects on psychological outcomes were only detected later because of the confrontation with emotionally charging topics. Furthermore, the results of studies by Baer et al [55] and Venkatesan et al [56] indicated that the effects on perceived stress might become (more) visible after a longer duration of the intervention. ...

... Despite our efforts to develop an evidence-based, practice-oriented, and easy to use decision rule, we had to deviate from the previous established conceptualization due to a considerable proportion of patients with a nonpathological baseline value in our sample (20%). Similar proportions have been reported in other samples (e.g., 29% in Rubel et al., 2015), suggesting that our modification is necessary to make the PI approach broadly applicable. By using ROC curve analysis, accounting for the relative cost of a false negative classification and the deterioration base rate of 10%, an optimal percentage change value of 35.24% was determined. ...

... HG therapy (Griffin & Tyrrell, 2003) is a psychotherapeutic approach with a growing evidence base (cf Attwood & Atkinson, 2020;Minami et al., 2013;Yates & Atkinson, 2011) which posits that individuals have innate emotional needs (Human Givens Institute, 2006) which, if not met in balance, can cause emotional distress. It draws on ideas from other counselling paradigms, including MI and CBT, to propose a holistic and practical framework for understanding what is needed to be mentally healthy. ...

... The measures and process of PCOMS do not emphasize a diagnostic, symptomatic, or theoretical lens, and they permit the clients to frame their distress in a manner that is consistent with their preferences and worldview. In a bench marking study, Reese et al. (2014) evaluated the effectiveness of using PCOMS with a racially diverse adult sample from low socioeconomic backgrounds with a depressive disorder and found effect sizes that were similar to broader ROM-focused clinical trial studies. ...

... Le score de changement « résidualisé » est en effet obtenu par la différence entre le score réellement observé à la fin du traitement chez le patient et le score de changement prédit par l'équation de régression, en tenant compte du score à l'entrée dans le traitement.14 Des données complémentaires sur cette méthodologie peuvent être trouvées dans l'article suivant :Minami et al. (2012). Benchmarking therapists : furthering the benchmarking method in its application to clinical practice.Quality and Quantity, 46, 6, 1699-1708. ...

... There have been some attempts to illustrate the dose-response relationship in studies on psychotherapies in depression (Barkham et al., 2006;Delgadillo et al., 2014;Erekson et al., 2015;Kadera et al., 1996;Lambert et al., 2001;Stulz et al., 2013), but there are only few systematic reviews on this subject (Cuijpers, Huibers, et al., 2013;Howard et al., 1986;. Original studies and the review by Howard et al. (1986) suggest a negatively accelerated dose-response curve with a stronger improvement in symptoms by Sessions 2-12, and then a flattening curve. ...

... Meta-analyses of treatment effects across various therapeutic approaches reveal that psychotherapies are generally equally effective (e.g., Baardseth et al., 2013;Leichsenring et al, 2003;Wampold et al., 1997;Wampold & Imel, 2015). Further analyses demonstrate that the treatment effect diminishes or even disappears when the therapist effect is controlled (Owen et al., 2015), indicating that factors related to the therapist may significantly influence the relationships between treatment and therapeutic outcomes. ...

... Namely, based on a sample of 18 therapists treating 158 couples, therapists with more years of Do Therapists Get Better with Experience? 5 couple's therapy experience had better client outcomes, although the effect size was small (Owen et al., 2014). Otherwise, each of the following newer studies found no relation between therapist experience and client outcome (because experience was defined differently, the specific measure used is noted): years post license 281 therapists and 10,812 clients); highest level of qualification and caseload (Chow et al., 2015;69 therapists and 4,580 clients); years of clinical experience (Delgadillo et al, 2018;49 therapists and 2,223 clients); license type and years of experience (Kraus et al., 2016;59 therapists and 3,540 clients); years of clinical experience and expert-rated clinical competence (Delgadillo et al, 2020; 69 therapists and 4,052 clients); trainee versus licensed professional (Laska et al., 2013;25 therapists and 192 clients);practicum, intern, or professional (Okiishi et al., 2003;91 therapists and 1,841 clients); degree and years of clinical experience (Wampold & Brown, 2005; 581 therapists and 6,146 clients). ...

... Psychotherapy research has consistently shown that specific characteristics of psychotherapists are not significantly correlated with their effectiveness. For example, the theoretical orientation (Anderson et al., 2009;Brown et al., 2005;Wampold & Brown, 2005), being in training or supervision (Budge et al., 2013;Nyman et al., 2010), or the number of years of experience (Goldberg et al., 2016), are not significant predictors for the increase of the effectiveness of clinical practice. Therapeutic outcomes are explained mainly by the difficulties therapists experience in their clinical practice and how they deal with them (Nissen-Lie et al., 2015). ...

... The data was limited to include clients' initial course of counseling across the 4 years of data collection to maintain independent observations at the client level and to prevent multiple courses of counseling for the same client from being included in the analyses. We defined one course of counseling as a group of appointments with no more than 90 days between appointments to indicate the end of one course of counseling and the start of a new course, which is an approach consistent with previous research analyzing longitudinal CCMH data (Hayes et al., 2016(Hayes et al., , 2020Lefevor et al., 2019;Minami et al., 2009). To analyze client symptoms at intake and the rate of change over the course of counseling, only clients who completed the first CCAPS administration within 14 days of their initial session and the last administration within 14 days of their final session were included. ...
