Of the 60 participants approached, 44 with majority of female (95%) completed the questionnaire. The mean age of participants was 25 years. Overall, participants reported low knowledge of CAM and attitudes towards CAM were positive. While 73% reported having recommended CAM to their clients, only 39% had ever made referral. Most of the participants (98%) had used CAM personally but just over half (59%) had ever used it in clinical practice. It was found that knowledge and attitudes towards CAM did not predict CAM recommendation, personal use, nor professional use among the participants. However, CAM knowledge was found to predict CAM referrals. It is assumed that positive attitudes towards CAM integration among participants has been conflicted with their concern for CAM safety.

A 26-item questionnaire was developed through an extensive literature search. Data was obtained from provisional psychologists from the Master of Professional Clinical Psychology programs at two established public universities in urban areas of Indonesia. To validate the questionnaire, panel reviews by executive members of the Indonesian Clinical Psychology Association (ICPA), experts in health psychology, and experts in public health and CAM provided their professional judgements. The self-reporting questionnaire consisted of four scales including: knowledge of CAM (6 items), attitudes towards CAM (10 items), CAM experiences (4 items), and CAM educational needs (6 items). All scales, except CAM Experiences, were assessed on a 7-point Likert scale. Sixty provisional psychologists were eligible to complete the questionnaire with a response rate of 73% (N = 44). The results showed that the CAM questionnaire was reliable (Cronbach's coefficient alpha range = 0.62-0.96; item-total correlation range = 0.14-0.92) and demonstrated content validity. Following further psychometric evaluation, the CAM questionnaire may provide the evidence-based information to inform the education and practice of Indonesian clinical psychologists.

Potential mediating variables of this association were explored. The relationship between corporal punishment and physical abuse was also investigated. DESIGN, SETTING AND SAMPLE: The children (N = 1226, 12-year olds) were selected from government schools in the Colombo district, using a stratified random sampling technique. Self-administered instruments, adapted and validated to the Sri Lankan context were used. The experience of parental corporal punishment was shown to be moderately, but significantly, associated with psychological maladjustment in children. This association was enhanced by the child witnessing or experiencing non-parent-to-child violence (eg. domestic, community, teacher and peer violence). The extent of the child's support network, the nature of the parent-child relationship and the child's attitude to corporal punishment did not significantly alte...

Research paper thumbnail of A child chronic cough-specific quality of life measure: development and validation

Cough is the most common symptom that results in new medical consultations. Although adult and parent-proxy cough-specific QoL instruments have been shown to be a useful cough outcome measure, no suitable cough-specific QoL measure for children with chronic cough exists. We report on the statistical properties of a chronic cough-specific QoL (CC-QoL) questionnaire for children. 130 children (median age 10 years, IQR 8-12 years; 65 girls) participated. A preliminary 37-item version was developed from conversations with children with chronic cough (>4 weeks). Children also completed generic QoL questionnaires (Pediatric QoL Inventory 4.0 (PedsQL4.0), Spence Children's Anxiety Scale (SCAS)) and cough diary scores. The clinical impact method of item reduction resulted in 16 items that had excellent internal consistency (Cronbach's α=0.94) among these items and also within each domain. Evidence for construct and criterion validity was established with significant correlations between CC-QoL subscales with cough scores, PedsQL and SCAS scores. CC-QoL scores were sensitive to change following an intervention and significant differences were noted between those children coughing and those who had ceased coughing. Minimum important difference (MID) for overall and domain CC-QoL ranged from 0.37-1.36 (distribution-based approach) to 1.11-1.58 (anchor-based approach). Chronic cough significantly impacts the QoL of children. The CC-QoL is a reliable, valid and sensitive to change outcome measure that assesses QoL from the child's perspective. Pending data from a confirmatory cohort, a MID for the CC-QoL of 1.1 is recommended when evaluating health status change.

A standard systematic translation procedure was followed to translate the original SURPS into Sinhala language. A Delphi process was conducted to determine judgmental validity of Sinhala SURPS. Confirmatory factor analysis was performed to test the translated version against the original theoretical model of the SURPS. Test-retest and internal consistency were used to ensure reliability. A few terms in one of the items posed some difficulty in translating into Sinhala. Adequate judgmental validity was determined except for one item, which was modified to suit the Sri Lankan setting. The four subscales introversion/ hopelessness, impulsivity, sensation seeking and anxiety sensitivity showed satisfactory test-retest reliability estimates of .74, .68, .76, and .88, respectively. The Sinhala SURPS is applicable in Sri Lankan context. Several implications based on the results are discussed.

Recent theorising on work–family interface suggests that work-related stress cannot be contained within the workplace without it impacting on other life domains such as the family. Similarly, it is claimed that family-related issues also affect what happens at work. The present study examined

Its validity has been demonstrated. This study sought to determine the minimally important difference (MID) for the PC-QOL completed by parents of young children with chronic cough. Thirty-four children (22 boys, 12 girls; median age, 26.5 months; interquartile range, 17.3-38.8 months) and their mothers participated. Mothers completed a cough-related measure (verbal category descriptive score) and the PC-QOL on two occasions separated by 2 to 3 weeks. Two approaches were used to calculate MID. Distribution-based approaches to estimating MID resulted in ranges of 0.50 to 0.78 (effect size method), 0.30 to 0.48 (SE of measurement method), and 0.60 to 0.69 (one-half SD method) for PC-QOL overall and domain scales. Based on verbal category descriptive score change, an anchor-based approach resulted in an MID estimate of 0.9 for overall PC-QOL change and ranged from 0.71 to 0.95 for individual domain PC-QOL change. An MID for the PC-QOL of 0.9 is recommended in interpreting health status change in children with chronic cough and will aid clinicians and researchers in interpreting health-related QOL changes following treatments and clinical trials.
