Background: Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness.Methods: The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments.Results: Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderate-vigorous physical activity was comparable to studies conducted in general population samples. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ.Conclusions: The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.

We studied the prevalence and possible association between exercise addiction and health in indoor cycling practitioners. In 1014 (492 women) adult indoor cyclists and 926 (597 women) controls with low levels of physical activity according to the short form of the International Physical Activity Questionnaire, we examined the risk of exercise addiction according to the Exercise Addiction Inventory and several health outcomes through a web-based experiment. The prevalence of a high risk of exercise addiction in cyclists was 13.3%, and it was higher in men than in women (16.5% vs. 10.0%, p = 0.002). Women cyclists with a high risk of exercise addiction had higher levels of physical activity (p < 0.001; effect size = −0.62, 95% CI: (−0.91, −0.32)) and anxiety symptom severity (p = 0.001; Effect Size (ES) = −0.59 (−0.89, −0.30)) than those with a low risk. For both sexes, cyclists with a low risk of exercise addiction had better social function, emotional role, and anxiety symptom severity compared with the controls (all p < 0.002; ES ranged from 0.25 to 0.47). Higher anxiety symptom severity and cardiorespiratory fitness were the main determinants of exercise addiction in cyclists (both p < 0.001). Our data suggest the importance of considering exercise addiction in indoor cyclists.

Aim: To transcultural adapt and analyze the reliability of Spanish version of Pregnancy Symptoms Inventory (PSI) and assess the prevalence of pregnancy symptoms in Spanish pregnant women. Materials and methods: A subsample of 120 healthy pregnant women answered the PSI twice and a sample of 280 report the prevalence and limitation of pregnancy symptoms. The reliability was examined by means of percent agreement and weighted Kappa coefficients. The prevalence of pregnancy symptoms was evaluated by the frequency of answers. Results: Perfect and perfect-acceptable agreement was observed in 82% and 96% of the pregnant women, respectively. Weighted Kappa coefficients ranged from 0.589 to 0.889, indicating a good reliability. The most frequent symptoms perceived by Spanish pregnant women were urinary frequency, poor sleep, increased vaginal discharge and tiredness. Conclusion: Spanish Pregnancy Symptoms Inventory is a brief, conceptually equivalent and satisfactory reliable tool that allows an early assessment of the wide range of pregnancy symptoms in the health care practices.
