The 1-repetition maximum (1RM) is defined as the maximum load that can be lifted just once in a given exercise. 1 The 1RM is one of the variables most commonly reported to assess the efficacy of various training and rehabilitation interventions as it is considered a valid indicator of maximal

The purpose of the present research was to develop questionnaires to assess outcome expectancy for resistance training (RT), behavioral expectation in the context of perceived barriers to RT, and self-regulation strategies for RT among young-old adults (50-69 years). Measurement development included (a) item generation through elicitation interviews (N = 14) and open-ended questionnaires (N = 56), (b) expert feedback on a preliminary draft of the questionnaires (N = 4), and (c) a quantitative longitudinal study for item-reduction and psychometric analyses (N = 94). Elicitation procedures, expert feedback, and item reduction yielded four questionnaires with a total of 33 items. Positive outcome expectancy (α = .809), negative outcome expectancy (α = .729), behavioral expectation (α = .925), and self-regulation (α = .761) had—with one exception—moderate bivariate associations with two different indicators of self-reported RT behavior at one-month follow-up (r = .298 to .506). The present research provides preliminary support for newly developed questionnaires to facilitate understanding of the psychosocial determinants of RT among young-old adults.

Measurement as a Persistent Challenge in the Study of Automatic Associations Compared with explicit constructs, implicit processes are greatly understudied and remain poorly understood.

The dearth of valid measures to assess transfer of responsibility learning in physical education or TPSR programs constitutes a gap in the literature ( Jacobs & Wright, 2017 ). The desire to see learning transfer is certainly not restricted to physical

The measure expresses the extent of accuracy to which the test material can evaluate the constructs, properties, roles or abilities for

Key Points ▸ The reliability of manual goniometry is highly dependent on the examiner. ▸ The concurrent validity of the inertial goniometer was very high compared to a 2D analysis. ▸ The ease of use, time efficiency, and concurrent validity supports the application of inertial goniometry. Range of

The study’s purpose is to describe the development and evaluate the reliability (inter-observer agreement) and validity (rater agreement with a gold standard) of a direct observation instrument to assess park characteristics that may be related to physical activity.
A direct observation instrument of 181 items was developed based on a conceptual model consisting of the following domains: features, condition, access, esthetics, and safety. Fifteen pairs of observers were trained and sent to two parks simultaneously to assess two Target Areas each.
Overall domain reliability was 86.9%, and overall geographic area reliability was 87.5%. Overall domain validity was 78.7% and overall geographic area validity was 81.5%.
Inter-rater reliability and validity were generally good, although validity was slightly lower than reliability. Objective items showed the highest reliability and validity. Items that are time-sensitive may need to be measured on multiple occasions, while items asking for subjective responses may require more supervised practice.
