The impact of therapeutic engagement on mental health outcomes in a short stay mental health unit.

 Abstract
Objective: To investigate the contribution of recovery-focused engagement and interventions in a 6 week stay non-acute inpatient unit for people with serious mental illness (SMI). More specifically, to investigate patterns of change for measures of clinical and personal recovery, and observe whether patterns of change are sustained at 6 month follow-up. A subsequent evaluation was conducted to investigate the association between change indices of therapeutic engagement, mental health outcomes and other key mental health measures. Methods: Twenty-seven people with SMI completed three self-report measures, one collaborative recovery measure and five clinician rated measures 2-3 days post-admission. Measures were repeated at discharge, 3 and 6-month follow-up. Twenty-three and 20 people respectively completed measures at the final two follow-up points. Results: Regression analysis found significant linear improvements in therapeutic engagement, symptomatology, functionality, self-determination and collaboratively determined recovery. A subcomponent of the recovery measure, social connectedness, also demonstrated linear improvement across follow-up periods with a large magnitude of change recorded. Therapeutic engagement and the initial change for the MHRS total score also showed conventionally large effect sizes (greater than 1). An association between therapeutic engagement and mental health outcomes; and mental health outcomes and functioning were also found. Conclusions: Although the study design incorporated limitations, the findings suggest that higher levels of wellness, self-determination and connectedness are achievable in a recovery-focused inpatient setting. The study also showed that these improvements were sustained at 6 month follow-up. However, given the limitations of this study, further work is required to explore the factors that overcome stigma and develop and sustain individual levels of hope in recovery.

Title: Quantifying Configural Superiority with the Capacity Coefficient.

Abstract: Inform
ally, configural superiority refers to situations in which perception is better with certain contextual information, beyond what would be expected from the informativeness of the context.  The nature of these effects are an important component of our understanding of visual perception of many types of stimuli and can be used diagnose privileged perceptual dimensions and potentially specialty perceptual systems.  We propose the capacity coefficient as common framework for measuring configural superiority across a wide range of stimulus types. This measure has a number of advantages. The coefficient is based on a comparison of responses to the configuration with a baseline of unlimited-capacity, independent, parallel processing of each of the parts. Response times for processing the parts in isolation are used to estimate that baseline performance. Better than baseline performance, or better than unlimited-capacity, independent parallel processing, of a configuration of parts, indicates configural superiority. Furthermore, because the capacity coefficient accounts for the difficulty of processing each part, the capacity coefficient for one type of configuration can be compared to the capacity coefficient of another configuration, even if the parts are not exactly the same. We applied the capacity coefficient to three domains in which configural superiority effects have been previously demonstrated: the orientation of a pair of dots, words, and faces. We found that participants had better than baseline performance for detecting differences in the location of dots relative to reference points if there was also a difference in the orientation. The capacity coefficient was much higher than when there was not a difference in orientation; in fact, when there was no difference in orientation, the capacity coefficient indicated worse than baseline performance. Likewise, we found that participants performed better than baseline with words. Participants’ capacity coefficients were higher for words than random consonant sequences, which tended to have equal to or worse than baseline capacity coefficients. Finally, we found that participants had better than baseline performance with aligned upper and lower face halves, but lower capacity coefficients with misaligned face halves, usually below baseline.
