Results are suggestive of positive effects of psychotherapy for infertile patients. However, these results must be viewed with caution due to methodological and informational bias within the studies analysed.
There are mixed findings regarding the differential efficacy of the group and individual format. One explanation of these mixed findings is that nearly all-recent meta-analyses use between-study effect sizes to test format equivalence introducing uncontrolled differences in patients, treatments, and outcome measures. Only 3 meta-analyses were located from the past 20 years that directly tested format differences in the same study using within-study effect sizes; mixed findings were reported with a primary limitation being the small number of studies. However, we located 67 studies that compared both formats in the same study. Format equivalence (g = -0.01) with low effect size heterogeneity (variability) was found in 46 studies that compared identical treatments, patients, and doses on primary outcome measures. Format equivalence (g = -0.06) with moderate effect size heterogeneity was found for 21 studies that compared nonidentical treatments; however, allegiance to a specific format moderated differences in effect sizes. There were no differences between formats for rates of treatment acceptance, dropout, remission, and improvement. Additionally, there were no differences in outcome between formats by patient diagnosis; however, differences in pre-to-post improvement were explained by diagnosis with depression, anxiety, and substance disorder posting the highest outcomes and medical and childhood disorders the lowest. Findings are discussed with reference to the practical challenges of implementing groups in clinical practice from an agency, clinician, and reimbursement perspective. (PsycINFO Database Record
Early change is an increasing area of investigation in psychotherapy research. In this study, we analyzed patterns of early change in interpersonal problems and their relationship to nonverbal synchrony and multiple outcome measures for the first time. We used growth mixture modeling to identify different latent classes of early change in interpersonal problems with 212 patients who underwent cognitive-behavioral treatment including interpersonal and emotion-focused elements. Furthermore, videotaped sessions were analyzed using motion energy analysis, providing values for the calculation of nonverbal synchrony to predict early change in interpersonal problems. The relationship between early change patterns and symptoms as well as overall change in interpersonal problems was also investigated. Three latent subgroups were identified: 1 class with slow improvement (n ϭ 145), 1 class with fast improvement (n ϭ 12), and 1 early deterioration class (n ϭ 55). Lower levels of early nonverbal synchrony were significantly related to fast improvement in interpersonal change patterns. Furthermore, such patterns predicted treatment outcome in symptoms and interpersonal problems. The results suggest that nonverbal synchrony is associated with early change patterns in interpersonal problems, which are also predictive of treatment outcome. Limitations of the applied methods as well as possible applications in routine care are discussed.Editor's Note. Sigal Zilcha-Mano served as the action editor for this article.-DMK Jr.
There is a growing body of literature recognizing the importance of outpatient psychotherapy. Several studies investigated the efficacy of outpatient psychotherapy and aspects of the health care system under natural conditions. This paper gives an overview of studies from German speaking countries (TRANS-OP-, TK-, PAP-S- and QS-PSY-BAY-study).The results of the different studies indicate both, positive outcome of the therapies (e. g., reduction of symptoms with an average ES of 1,03; improvement of symptoms despite premature termination) as well as an economic benefit (end of treatment depending on treatment outcome and not limited by therapy sessions; extensions of psychotherapy only if patient is highly impaired and therapeutic alliance is positive; high reduction of supply costs and sick leave). However, the low health care density in rural areas and the waiting periods before starting therapy are indicators of structural problems of the health care system with respect to outpatient psychotherapy.The efficacy of outpatient psychotherapies under natural conditions is sufficiently supported. Future studies should investigate structural aspects of the health care system, for example by focussing on the establishment of inter-sectoral connections between different professional groups and a reduction of bureaucratic actions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
