TENDINopathy Severity assessment-Achilles (TENDINS-A): evaluation of reliability and validity in accordance with COSMIN recommendations.

OBJECTIVE: To evaluate the construct validity (structural validity and hypothesis testing), reliability (test-retest reliability, measurement error and internal consistency) and minimal important change (MIC) of the 13-item TENDINopathy Severity assessment-Achilles (TENDINS-A). METHODS: Participants with Achilles pain completed an online survey including: demographics, TENDINS-A, Foot and Ankle Outcome Score (FAOS) and Victorian Institute of Sport Assessment-Achilles (VISA-A). Exploratory factor analysis (EFA) assessed dimensionality. Confirmatory factor analysis (CFA) assessed structural validity (root mean square error of approximation (RMSEA); Comparative Fit Index (CFI); Tucker-Lewis Index (TLI); standardised root measure square (SRMS)). Correlations between TENDINS-A and the FAOS or VISA-A assessed hypothesis testing. Intraclass correlation (ICC) assessed test-retest reliability. Cronbach's alpha assessed internal consistency. SE of the measurement (SEM) assessed measurement error. A distribution-based approach assessed MIC. RESULTS: 79 participants (51% female) with a mean (SD) age=42.6 (13.0) years, height=175.0 (11.7) cm and body mass=82.0 (19.1) kg were included. EFA identified three meaningful factors, proposed as pain, symptoms and function. The best model identified using CFA for TENDINS-A had structural validity (RMSEA=0.101, CFI=0.959, TLI=0.947, SRMS=0.068), which included three factors (pain, symptoms and function), but excluded three items from the original TENDINS-A. TENDINS-A exhibited moderate positive correlation with FAOS (r=0.598, p<0.001) and a moderate negative correlation with VISA-A (r=-0.639, p<0.001). Reliability of the TENDINS-A was excellent (ICC=0.930; Cronbach's α=0.808; SEM=6.54 units), with an MIC of 12 units. CONCLUSIONS: Our evaluation of the revised 10-item TENDINS-A determined it has construct validity and excellent reliability, compared with the VISA-A and FAOS which lack content and construct validity. The TENDINS-A is recommended as the preferred patient-reported outcome measure to assess disability in people with Achilles tendinopathy.

Promoting physical activity in regional and remote cancer survivors (PPARCS) using wearables and health coaching: randomised controlled trial protocol.

INTRODUCTION: Physically active cancer survivors have substantially less cancer recurrence and improved survival compared with those who are inactive. However, the majority of survivors (70%-90%) are not meeting the physical activity (PA) guidelines. There are also significant geographic inequalities in cancer survival with poorer survival rates for the third of Australians who live in non-metropolitan areas compared with those living in major cities. The primary objective of the trial is to increase moderate-to-vigorous PA (MVPA) among cancer survivors living in regional and remote Western Australia. Secondary objectives are to reduce sedentary behaviour and in conjunction with increased PA, improve quality of life (QoL) in non-metropolitan survivors. Tertiary objectives are to assess the effectiveness of the health action process approach (HAPA) model variables, on which the intervention is based, to predict change in MVPA. METHODS AND ANALYSIS: Eighty-six cancer survivors will be randomised into either the intervention or control group. Intervention group participants will receive a Fitbit and up to six telephone health-coaching sessions. MVPA (using Actigraph), QoL and psychological variables (based on the HAPA model via questionnaire) will be assessed at baseline, 12 weeks (end of intervention) and 24 weeks (end of follow-up). A general linear mixed model will be used to assess the effectiveness of the intervention. ETHICS AND DISSEMINATION: Ethics approval has been obtained from St John of God Hospital Subiaco (HREC/#1201). We plan to submit a manuscript of the results to a peer-reviewed journal. Results will be presented at conferences, community and consumer forums and hospital research conferences. TRIAL REGISTRATION NUMBER: ACTRN12618001743257; pre-results, U1111-1222-5698.

Knowledge, attitudes, and practice of oncologists and oncology health care providers in promoting physical activity to cancer survivors: an international survey.

OBJECTIVE: To investigate knowledge, attitudes, and practices of oncologists towards physical activity (PA) in cancer survivors, and the association between oncologists' own PA behavior and PA promotion. METHODS: Oncologists (n = 123) completed a survey based on the Theory of Planned Behavior (TPB). Participants reported PA promotion behavior, PA involvement, attitudes, intentions, social norm, perceived behavioral control (PBC), and confidence and knowledge of exercise prescription. Structural equation modeling (SEM) evaluated these associations. RESULTS: Less than half of oncologists reported regularly promoting PA to patients (46%), with 20% providing written information and 23% referrals. Only 26% were physically active. TPB SEM pathways explained 54.6% of the variance in PA promotion (comparative fit index (CFI) = 0.905, standardized root mean square residual (SRMR) = 0.040). Social norm was not only the significant pathway to intention but also a significant indirect pathway to PA promotion (p = 0.007). Confidence to promote PA, PBC, and intentions were direct significant pathways to PA promotion (p < 0.05). Exploratory SEM pathways explained 19.6% of the variance of PA behavior, which in turn explained 13.1% social norm, 10.7% attitude, 10.0% confidence to recommend, and 17.8% PA promotion behavior (CFI = 0.921, SRMR = 0.076). Instrumental attitude was a direct significant pathway to PA behavior (p = 0.001). PA behavior was a direct significant pathway to social norms, attitude, confidence to recommend, and PA promotion (p < 0.05). CONCLUSIONS: Oncologists reported a modest ability to promote PA, low PA promotion rates, and limited knowledge of exercise prescription. Patient physical activity promotion may be improved through strategies that increase oncologists' PBC, confidence, and their own personal PA participation.

Grip and Muscle Strength Dynamometry in Acute Burn Injury: Evaluation of an Updated Assessment Protocol.

External stabilization is reported to improve reliability of hand-held dynamometry, yet this has not been tested in burns. We aimed to assess the reliability of dynamometry using an external system of stabilization in people with moderate burn injury and explore construct validity of strength assessment using dynamometry. Participants were assessed on muscle and grip strength three times on each side. Assessment occurred three times per week for up to 4 weeks. Within-session reliability was assessed using intraclass correlations calculated for within-session data grouped before surgery, immediately after surgery and in the subacute phase of injury. Minimum detectable differences were also calculated. In the same timeframe categories, construct validity was explored using regression analysis incorporating burn severity and demographic characteristics. Thirty-eight participants with total burn surface area 5% to 40% were recruited. Reliability was determined to be clinically applicable for the assessment method (intraclass correlation coefficient >0.75) at all phases after injury. Muscle strength was associated with sex and burn location during injury and wound healing. Burn size in the immediate period after surgery and age in the subacute phase of injury were also associated with muscle strength assessment results. Hand-held dynamometry is a reliable assessment tool for evaluating within-session muscle strength in the acute and subacute phase of injury in burns up to 40% total burn surface area. External stabilization may assist to eliminate reliability issues related to patient and assessor strength.

Perceptions of barriers to discussing and testing for sexually transmitted infections in a convenience sample of general practice patients.

We aimed to identify patient perceptions of barriers to discussing sexually transmitted infections (STIs) at the primary care level. An anonymous questionnaire was available to patients (16-70 years) in the waiting room of four metropolitan Perth general practices. Results are based on 370 participant views (9.5% of the potential target population). Patients felt comfortable discussing STIs with their general practitioner (GP) and their level of comfort would be enhanced if they knew their GP had a special interest or qualification in sexual health. Willingness to discuss issues increased or remained unchanged if the GP took time to explain it to them or was a good listener. Patients were willing to discuss STIs if they were a new patient and irrespective of the GP's gender and age. Fewer patients were willing to discuss STIs if they knew the GP socially. Patients who had sex with a new partner were willing to request a STI test from their GP. Patients were not embarrassed if discussion was initiated in a consultation unrelated to sexual health and did not mind discussing the topic in the presence of a partner or parent, though this depended on circumstances. Waiting room STI test advertising did not affect patient comfort level. Patients would involve their GP when seeking information about STIs. Patients have fewer barriers to discussing sexual health matters than perceived by GPs.
