“…This analysis provided model fit statistics, which allowed the relative strengths of exploratory-derived factor solutions to be assessed without the need for specifying the factor structure in advance (Mora et al, 2011; Marsh et al, 2013). …”

Social Reward Questionnaire (SRQ): development and validation

et al. 2014

Human beings seek out social interactions as a source of reward. To date, there have been limited attempts to identify different forms of social reward, and little is known about how the value of social rewards might vary between individuals. This study aimed to address both these issues by developing the Social Reward Questionnaire (SRQ), a measure of individual differences in the value of different social rewards. Exploratory factor analysis (EFA) was run on an initial set of 75 items (N = 305). Based on this analysis, confirmatory factor analysis (CFA) was then conducted on a second sample (N = 505) with a refined 23-item scale. This analysis was used to test a six-factor structure, which resulted in good model fit (CFI = 0.96, RSMEA = 0.07). The factors represent six subscales of social reward defined as follows: Admiration; Negative Social Potency; Passivity; Prosocial Interactions; Sexual Reward; and Sociability. All subscales demonstrated good test-retest reliability and internal consistency. Each subscale also showed a distinct pattern of associations with external correlates measuring personality traits, attitudes, and goals, thus demonstrating construct validity. Taken together, the findings suggest that the SRQ is a reliable, valid measure that can be used to assess individual differences in the value experienced from different social rewards.

“…The primary behavioral outcome was self-reported medication adherence measured by postal questionnaire sent 1 week before visit 2 (8 weeks) using the Medication Adherence Report Scale (MARS) developed by Horne and colleagues [18]. We used a five-item version of the MARS that asked about “using your diabetes medicines in the last month”, with item responses scored on a 5-point scale from “always true” [1] to “never true” [5].…”

Does Electronic Monitoring Influence Adherence to Medication? Randomized Controlled Trial of Measurement Reactivity

et al. 2014

View full text Add to dashboard Cite

BackgroundElectronic monitoring is recommended for accurate measurement of medication adherence but a possible limitation is that it may influence adherence.PurposeTo test the reactive effect of electronic monitoring in a randomized controlled trial.MethodsA total of 226 adults with type 2 diabetes and HbA1c ≥58 mmol/mol were randomized to receiving their main oral glucose lowering medication in electronic containers or standard packaging. The primary outcomes were self-reported adherence measured with the MARS (Medication Adherence Report Scale; range 5–25) and HbA1c at 8 weeks.ResultsNon-significantly higher adherence and lower HbA1c were observed in the electronic container group (differences in means, adjusting for baseline value: MARS, 0.4 [95 % CI −0.1 to 0.8, p = 0.11]; HbA1c (mmol/mol), −1.02 [−2.73 to 0.71, p = 0.25]).ConclusionsElectronic containers may lead to a small increase in adherence but this potential limitation is outweighed by their advantages. Our findings support electronic monitoring as the method of choice in research on medication adherence. (Trial registration Current Controlled Trials ISRCT N30522359)

“…These validated questionnaires, in addition to a structured data collection form, will be used to determine current asthma therapy and control, current asthma triggers and co-morbidity and past history including frequency of oral corticosteroid use and previous hospital admissions for asthma. In addition, data will be collected on smoking (direct and passive exposure), Quality of Life (Mini Asthma Quality of Life Questionnaire [32]) and psychological variables using the Perceived Control of Asthma Questionnaire [33], Brief Illness Perception Questionnaire [34], Medical Adherence Report Scale-Asthma [35], Patient-Clinician Communication Questionnaire [36], Beliefs About Medicines Questionnaire [37], Teratogenic Risk Perception Questionnaire [38], and a purpose designed Asthma Knowledge Questionnaire. For all participants blood will be drawn for total IgE and RAST testing to assess atopy.…”

BackgroundPregnancy presents a unique situation for the management of asthma as it can alter the course of asthma severity and its treatment, which in turn can affect pregnancy outcomes. Despite awareness of the substantial adverse effects associated with asthma during pregnancy, little has been done to improve its management and reduce associated perinatal morbidity and mortality. The aim of this randomized controlled trial is to evaluate the clinical and cost effectiveness of an Antenatal Asthma Management Service.Methods/designDesign: Multicentre, randomized controlled trial.Inclusion criteria: Women with physician diagnosed asthma, which is not currently in remission, who are less than 20 weeks gestation with a singleton pregnancy and do not have a chronic medical condition.Trial entry and randomization: Eligible women with asthma, stratified by treatment site, disease severity and parity, will be randomized into either the ‘Standard Care Group’ or the ‘Intervention Group’.Study groups: Both groups will be followed prospectively throughout pregnancy. Women in the ‘Standard Care Group’ will receive routine obstetric care reflecting current clinical practice in Australian hospitals. Women in the ‘Intervention Group’ will receive additional care through the nurse-led Antenatal Asthma Management Service, based in the antenatal outpatient clinic. Women will receive asthma education with a full assessment of their asthma at 18, 24, 30 and 36 weeks gestation. Each antenatal visit will include a 60 min session where asthma management skills are assessed including: medication adherence and knowledge, inhaler device technique, recognition of asthma deterioration and possession of a written asthma action plan. Furthermore, subjects will receive education about asthma control and management skills including trigger avoidance and smoking cessation counseling when appropriate.Primary study outcome: Asthma exacerbations during pregnancy.Sample size: A sample size of 378 women will be sufficient to show an absolute reduction in asthma exacerbations during pregnancy of 20% (alpha 0.05 two-tailed, 90% power, 5% loss to follow-up).DiscussionThe integration of an asthma education program within the antenatal clinic setting has the significant potential to improve the participation of pregnant women in the self-management of their asthma, reduce asthma exacerbations and improve perinatal health outcomes.Trial registrationACTRN12613000244707
