Psychometric properties of the Adolescent Motor Competence Questionnaire for Norwegian adolescents

The objective of this study was to examine the psychometric properties of the Adolescent Motor Competence Questionnaire (AMCQ) for Norwegian adolescents. To this end, a sample of 349 Norwegian-speaking adolescents (13-16 years old) were recruited and completed the AMCQ. Initial results showed that confirmatory factor analysis (CFA) did not indicate statistical support for previous statistical models reported in the literature. Further analysis indicated factorial validity for a novel three-factor model identified through exploratory factor analysis, encompassing measures of fine motor skill (α = 0.65), gross motor skill (α = 0.74), and activities of daily living (ADL; α = 0.79) with acceptable internal consistency coefficients. Subsequent analysis indicated indices of measurement invariance in the study sample, as males rated their competence higher compared to females in 19 of the 27 items, and better model fit was obtained for the female adolescents. Strong invariance was tenable, and no factor mean differences were found across older and younger adolescents or across BMI scores. Overall results thus suggested that the AMCQ has acceptable psychometric properties and can be confidently used in further work with perceived motor competence in Norwegian 13-16 years-old adolescents.

Self-Report Motor Competence in Adolescents Aged 12-18 Years in Regional and Rural Victoria (Australia)

Background: Poor motor skills are an increasing issue for adolescents in our local communities. In regional Victoria, almost 20% of children starting school in 2018 were considered at risk or developmentally vulnerable in the domain of physical health and wellbeing. Purpose: The aim of the current study was to examine factors (how adolescents perceive their fine and gross motor skills, activities of daily living, comparison to peers) of motor competence that may be important to adolescents in regional Victoria, Australia, using the Adolescent Motor Competence Questionnaire (AMCQ). Methods: A sample of 183 Australian adolescents ([138 females (M_age = 15.59 years, SD = 1.56); 45 males, (M_age = 15.82 years, SD = 1.95); 12-18 years old] completed the AMCQ. Results: The mean AMCQ score was 87.86 (SD = 7.55), with no significant difference between males (M = 89.67 SD = 7.29) and females [M = 87.28 SD = 7.56; t (181 = 1.86 p =.065)]. A Principal Component Analysis (PCA), extracted five factors (Eiqenvalue of 1.389) explaining 43.46% of variance, representing, Ball Skills and Kinesthesis; Activities of Daily Living; Fine Motor and Gross Motor; Proprioception and Exteroception; Public Performance. Conclusion: The results highlight key factors important in describing an adolescent's motor competence within regional Victoria. With physical health a priority in local communities, understanding these factors is an important first, that which may inform development of physical activity interventions for adolescents.

Does level of motor competence affect the associations between identity health and self-perceptions in adolescents?

BACKGROUND

Adolescence is a particularly important time for the development of self-perceptions and identity as many environmental and personal factors are influential. One relatively unexplored factor is level of motor competence.

AIM

To examine the relationship between identity health and self-perceptions in male and female adolescents with low motor competence (LMC) compared to typically developing (TD) adolescents.

METHOD

Adolescents (N = 160, 64.4% males, M_age = 14.45 yrs., SD = 0.75) completed the Adolescent Motor Competence Questionnaire (AMCQ), Assessment of Identity Development in Adolescence (AIDA), and Harter's Self-Perception Profile for Adolescents (SPPA). Based on the AMCQ score, the sample was grouped into LMC and TD. Pearson's product moment correlations between the AIDA and SPPA subscales were derived for gender, competence groups, and gender x competence sub-groups.

RESULTS

Overall, males had lower AIDA scores (healthier identity) than the females and significant associations with all self-perception domains. For females, only scholastic and social competence, physical appearance, behavioural conduct, close friendship and Global Self-worth (GSW) domains were significantly related to their AIDA score. The adolescents in the LMC group had higher AIDA scores (less-healthier identity) and fewer self-perception domains [scholastic competence, physical appearance, behavioural conduct, close friendships and GSW] were associated to their AIDA scores. For the TD group, all self-perception domains were significantly correlated with their AIDA scores. When grouped by gender and motor competence, the TD males had the healthiest identity scores which were strongly associated with all self-perception subdomains. For males with LMC, only scholastic competence, behavioural conduct and GSW domains were significantly related with their identity score. Females from both competence groups reported significant associations between physical appearance, close friendships, behavioural conduct, and social competence domains with their identity scores. Scholastic competence was also significantly associated with identity only for females with LMC.

CONCLUSION

Positive self-perceptions across a range of domains are associated with a healthier identity, but differ according to level of motor competence and gender. For those with LMC, the self-perception subdomains unrelated to physical activity and sport, such as school-based aspects were associated with a healthier identity. These findings should guide school based interventions to provide support in these domains in order to strengthen self-worth and identity health.
