BackgroundPatient self-report allows collecting comprehensive data for the purpose of performing economic evaluations. The aim of the current study was to assess the feasibility, reliability and a part of the construct validity of a commonly applied questionnaire on healthcare utilization and productivity losses in patients with a psychiatric disorder (TiC-P).MethodsData were derived alongside two clinical trials performed in the Netherlands in patients with mental health problems. The response rate, average time of filling out the questionnaire and proportions of missing values were used as indicators of feasibility of the questionnaire. Test-retest analyses were performed including Cohen’s kappa and intra class correlation coefficients to assess reliability of the data. The construct validity was assessed by comparing patient reported data on contacts with psychotherapists and reported data on long-term absence from work with data derived from registries.ResultsThe response rate was 72%. The mean time needed for filling out the first TiC-P was 9.4 minutes. The time needed for filling out the questionnaire was 2.3 minutes less for follow up measurements. Proportions of missing values were limited (< 2.4%) except for medication for which in 10% of the cases costs could not be calculated. Cohen’s kappa was satisfactory to almost perfect for most items related to healthcare consumption and satisfactory for items on absence from work and presenteeism. Comparable results were shown by the ICCs on variables measuring volumes of medical consumption and productivity losses indicating good reliability of the questionnaire.Absolute agreement between patient-reported data and data derived from medical registrations of the psychotherapists was satisfactory. Accepting a margin of +/− seven days, the agreement on reported and registered data on long-term absence from work was satisfactory. The validity of self-reported data using the TiC-P is promising.ConclusionsThe results indicate that the TiC-P is a feasible and reliable instrument for collecting data on medical consumption and productivity losses in patients with mild to moderate mental health problems. Additionally, the construct validity of questions related to contacts with psychotherapist and long-term absence from work was satisfactory.

Summary Objective Maintaining weight loss results in childhood obesity treatment is difficult to achieve. Self‐management techniques such as self‐monitoring are associated with increased weight loss and maintenance. This study analyzes whether self‐monitoring of lifestyle behaviours through a short message service maintenance treatment (SMSMT) via mobile phones with personalized feedback positively effects weight, lifestyle behaviours and psychological well‐being in obese children. Methods After 3 months of behavioural lifestyle treatment, 141 overweight and obese children (7–12 years) were randomly assigned to an intervention group receiving SMSMT for 9 months (n = 73) or to the control group (n = 68). The intervention group sent weekly self‐monitoring data on exercise and eating behaviour and their mood via mobile phones. In return, they received tailored feedback messages. Primary treatment outcomes were weight, eating behaviour and psychological well‐being, i.e. competence, self‐esteem and quality of life. Secondary outcome was adherence to the SMSMT. Data were analyzed with mixed modelling. Results SMSMT did not improve treatment outcomes. Controls gained temporarily in physical health scores (P = 0.01). SMSMT completers sent on average every 2 weeks an SMS. Children who had greater weight loss during the first 3 months of lifestyle treatment sent more SMSs (P = 0.04). Conclusions We did not find a positive effect of SMSMT on weight, eating behaviour or psychological well‐being in obese children. SMSMT seems to be a feasible method of treatment delivery. Future research should study variations of SMSMT to investigate how SMSMT can be more effective.

The 3-year psychological effects of presymptomatic DNA diagnosis for Huntington's disease are described in 20 identified carriers of the Huntington's disease gene (mean age = 31 years), 29 noncarriers (mean age = 32 years), and 37 partners. The Intrusion and Avoidance subscales of the Impact of Event Scale (M. J. Horowitz, N. Wilner, & W. Alvarez, 1979) and the Beck Hopelessness Scale (A. T. Beck, 1986; A. T. Beck, A. Weissman, D. Lester, & L. Trexler, 1974) measured psychological distress at 4 time points: baseline (before disclosure of test results) and 1 week, 6 months, and 3 years after testing. Multivariate testing on course of distress revealed similar patterns of intrusive thoughts about Huntington's disease over the 3-year follow-up in carriers and noncarriers but showed opposite patterns of avoidance at the 6-month assessment. One week after disclosure, carriers had increased and noncarriers had decreased levels of hopelessness. These effects disappeared after 6 months and did not recur. Carrier partners followed the same course of distress as carriers. Carrier partners with children were significantly more distressed than those without offspring. Noncarrier partners were significantly less distressed than noncarriers after 3 years.

The 7-10-year psychological effects of presymptomatic testing for Huntington disease are described in 142 individuals and 104 partners. Questionnaires included the Beck Hopelessness Scale (A. T. Beck, A. Weissman, D. Lester, & L. Trexler, 1974), the Impact of Event Scale (M. J. Horowitz, N. Wilner. & W. Alvarez. 1979). and the General Health Questionnaire (D. P. Goldberg. 1972). Carriers and their partners were more distressed immediately after the test result, although their outlooks improved somewhat in the 2-3-year posttest period. However, they became more pessimistic thereafter, when approaching the age of onset. Carriers, who were lost to follow-up after disclosure of test results, reported more distress pretest than did retained carriers. This demonstrates that studies that report few harmful effects may have underestimated the real impact. Moreover, follow-up studies need to investigate time effects for longer than a few years.
