“…In keeping with previous voices research, we applied a change of ±3 as the MCI, derived from expert opinion (Hayward et al, 2017). A more robust method could utilize the Reliable Change Index (Jacobson & Truax, ; Ronk, Hooke, & Page, ), where clinical significance is operationalized by using a cut‐off value marking the transition between people who are functioning well and those who need care.…”

Brief and single-symptom forms of cognitive behaviour therapy (CBT) for distressing voices may increase access to evidence-based psychological therapy and transcend diagnostic barriers. The current study evaluated the "C" and "B" in CBT for distressing voices in a transdiagnostic voices clinic. The B module (component of therapy) sought to enhance coping with voices, and the C module evaluated the accuracy of negative beliefs about the self and voices. The aims of the study were to investigate (a) whether modules B and/or C led to significant and clinically meaningful improvements on the primary outcome of voice-related distress, and (b) if changes in beliefs about self and voices (proposed change mechanisms) underpinned changes in voice distress across module C. Each module consisted of four sessions, individually tailored yet manualized, and designed with ease of staff training and delivery in mind. Assessment measures were administered at baseline (T1), post-module B (T2), and postmodule C (T3). The results (N = 62) showed statistically significant medium-sizedpre-and post-effects for voice-related distress from T1 to T2 and from T2 to T3, with large effects from T1 to T3. Just over half of the clients reported clinically meaningful improvements from T1 to T3. Neither beliefs about self nor voices were found to mediate improvements in voice distress during module C. The findings from this study suggest that both the B and C in CBT for voices can contribute to positive outcomes within routine clinical practice.

Longitudinal Estimation of the Clinically Significant Change in the Treatment of Major Depression Disorder

Background: Although major depressive disorder is usually treated with antidepressants, only 50–70% of the patients respond to this treatment. This study applied Jacobson and Truax’s (1991) methodology (reliable change index, RCI) to a sample of depressive patients being treated with one of two antidepressants to evaluate their functioning and the effect of certain variables such as severity and age.Method: Seventy-three depressive patients medicated with Escitalopram (n = 37) or Duloxetine (n = 36) were assessed using the Hamilton depression rating scale over a 24-week period.Results: They indicate that the RCI stabilizes in an absolute way starting in week 16, and it is not until week 24 that all of the patients become part of the functional population. We found limited statistical significance with respect to the RCI and the external variables.Conclusion: Our study suggests the need to accompany the traditional statistical methodology with some other clinical estimation systems capable of going beyond a simple subtraction between pre and posttreatment values. Hence, it is concluded that RCI estimations could be stronger and more stable than the classical statistical techniques.

“…One style of feedback delivery system incorporates graphical, highlighted areas in addition to a "traffic light" presentation to inform the patient and therapist of progress and areas of concern. For instance, the feedback using the OQ-Analyst package (that accompanies the 45-item Outcome Questionnaire; OQ45; Lambert & Finch, 1999) is based on calculations involved in estimating clinical significance (Jacobson & Truax, 1991) (Ronk, Hooke, & Page, 2016;Ronk, Korman, Hooke, & Page, 2013). The threshold for movement from the "unhealthy" into the "healthy" range is identified and the session-to-session change can be reliably and validly compared against the pre-treatment score (Ronk, Hooke, & Page, 2012;Ronk et al, 2016).…”

Whilst feedback is demonstrated to improve therapy outcomes, little attention has been given to the relative benefits of the form in which feedback is given. The present study aimed to compare patients' perceptions of feedback graphs with and without expected treatment response trajectories. In a counterbalanced design, patients in two-week CBT programs were shown feedback graphs with and without expected symptom trajectories; and were asked to complete questionnaire regarding the appeal after viewing the first graphs. Patients (n=42) viewed feedback graphs and preferred those with trajectories present and perceived the additional detail helpful to both themselves and their therapists. The present findings support the appeal for and potential usefulness of richer feedback for facilitating discussion and positive outcomes in therapy.
