ABSTRACT To determine if readiness for change (RFC) at admission predicted length of stay (LOS) and short-term outcomes among female adolescents in residential treatment for anorexia nervosa (AN).
Using a prospective cohort design to collect data from participants (N = 65) at admission and discharge, Kaplan-Meier survival analysis and Cox regression tested whether RFC on admission predicted time in LOS to a favorable short-term outcome--a composite endpoint based on minimum criteria for weight gain, drive for thinness, depression, anxiety, and health-related quality of life (HRQOL).
Participants with low RFC had a mean survival time to a favorable short-term outcome of 59.4 days compared to 34.1 days for those with high RFC (log rank = 8.44, df = 1, p = .003). The probability of a favorable short-term outcome was 5.30 times greater for participants with high RFC.
Readiness for change is a useful predictor of a favorable short-term outcome and should be considered in the assessment profile of patients with AN.

    ABSTRACT: People with eating disorders (ED) often report poor health-related quality of life (HRQoL), which is explicitly correlated to illness' severity and its effects on cognitive performance. We aimed to analyze health-related quality of life (HRQoL) in subgroups of eating disorder (ED) patients by using the brief version of WHOQoL questionnaire (WHOQoL-BREF) before treatment administration. Moreover, in order to compare our findings with other published data, we carried out a comprehensive review of the literature on HRQoL in ED patients.

    ABSTRACT: Accessible summaryBrief manualized training over a 4-week period in motivational interviewing (MI) in conjunction with patient worksheets, session audio recordings and independent ratings of adherence and competence resulted in mental health nurses (MHNs) on an inpatient eating disorder ward significantly improving their MI adherence and competence.Despite the brevity of the training, MHNs' satisfaction with the training was high.When compared with a similar time period on the ward before MI training, premature discharge rates were significantly lower after MI was utilized by the nurses.AbstractThis study examined whether: (1) brief training in motivational interviewing (MI) can prepare mental health nurses (MHNs) to provide MI to patients; and (2) this MI impacts on patients with respect to premature discharge. Six MHNs on an inpatient eating disorder unit were trained in MI, and their treatment adherence and competence were evaluated at post-training and 2-month follow-up. Premature discharge was examined by comparing a 3-month period in 2009 before MI administration with 2010 when MI was being administered. MHNs significantly improved their MI adherence and competence. Satisfaction with the training was high as was patient satisfaction with MI. Premature discharge rates significantly decreased. Brief training in MI is sufficient to significantly increase competency and adherence in the practice of MI by MHNs, which may in turn be effective in improving patients' treatment adherence by reducing premature discharge rates. Future research will need to utilize a randomized controlled design in order to further investigate these findings.

    ABSTRACT: Engaging patients with an eating disorder in change is difficult and intensive treatment programs have high drop-out rates. The purpose of the study was to determine whether Motivational Interviewing (MI) in the form of a brief, pre-treatment intervention would be associated with higher completion rates in subsequent intensive treatment for an eating disorder. Thirty-two participants diagnosed with an eating disorder participated in the study. All participants were on the waitlist for admission to an intensive, hospital-based treatment program. Sixteen participants were randomly assigned to four individual sessions of MI that began prior to entrance into the treatment program (MI condition) and 16 participants were assigned to treatment as usual (control condition). The main outcome was completion of the intensive treatment program. Participants also completed self-report measures of motivation to change.
