Introduction
I recently got my PhD on psychosocial effects of surgery and physical activity in bariatric patients. Currently, I'm (still) a young researcher interested in topics related with social inequalities, vulnerable/clinical populations, and self-determination theory. I have also becoming interested in the validation and adjustment of questionnaires to assess physical activity in young populations.

Questions

Questions (11)
Question
I am interested in knowing if there is any research work exploring factors that may affect the way in which girls and boys (aged 9-12 yrs.) complete physical activity self-report measures (e.g., questionnaires). Do you know of any studies that indicate that girls record/adjust their subjective physical activity better (compared to device-measured physical activity) than boys?
Question
Hello everybody! We are carrying out a research where we associate baseline to post-intervention changes between motivation and physical activity variables. My question is the following: In an experimental group, if I have a NEGATIVE association between INCREASES in introjected regulation and DECREASES in sedentary activity, how should I interpret it? Do you have any example of reference that describes this type of results between changes or similar? Many thanks in advance! Cheers.
Question
Hello everybody. I am interested in conducting a study with data from a randomized study we did in 2010. However, we did not register the trial on pages like ClinicalTrials.gov in that year. Is it possible to do it now? Implications? Problems with reviewers? Possible solutions?
Question
I'm looking for validated instruments to measure drug and alcohol use in adolescents, or even causes or risk factors that lead (or not) to this type of behaviour.
Question
I want to do a systematic review about this and I need a lot of articles. Can you help me? Thank you very much!
Question
WHO says that health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
Question
I'm interested in knowing possible variations that you would do and your opinions.
Question
For example, to analyze weekdays and weekend physical activity patterns. Thank you.
