Perceived neighborhood environments and physical activity in an elderly sample

Increasing evidence indicates the importance of environmental variables in explaining physical activity. This study evaluated sex differences in perception of home and neighborhood environmental support and assessed which neighborhood environmental variables were associated with reported physical activity of elderly people. A sample of 126 women (M age = 79.1 +/- 6.6 yr.) and 55 men (M age = 76.6 +/- 7.7 yr.) were healthy, community-dwelling individuals. A questionnaire about environmental variables was administered. Physical activity was assessed on the Baecke Questionnaire. Logistic regression analysis showed that Neighborhood Safety was related to total physical activity, activity in leisure time, and sport activities. Men were also likely to be more active in leisure time than women. Neighborhood Personal Safety was associated with physical activity of these elderly people, showing a potential influence of the environmental domain in physical activity.     

Assessing the Rising Emphasis on Muscularity for Women: Psychometric Properties of the Brazilian Version of the Female Muscularity Scale

The female appearance ideal has undergone considerable changes in recent years, resulting in increases in drive for muscularity among Brazilian women. The Female Muscularity Scale (FMS) was developed to assess muscularity concerns among U.S. women and was shown to be a promising measure of muscularity-related attitudes and behaviors. The present studies aimed to translate and culturally adapt the FMS to Brazilian Portuguese and to explore its factorial structure among Brazilian women (Study 1: n = 202, M_age = 24.40, SD = 5.03) and to confirm the factor structure as well as evaluate convergent and divergent validity and reliability of the FMS for young adult Brazilian women (Study 2: n = 382, M_age = 22.71, SD = 4.32). Exploratory factor analysis revealed a two-factor structure (Attitudes and Behaviors subscales), each comprising five items. Confirmatory factor analysis upheld the original two-factor structure with good fit indices. The full scale and its subscales presented convergent validity through associations with measures of body dissatisfaction, drive for muscularity, body-ideal internalization, body checking and avoidance behaviors, disordered eating, and exercise engagement. Evidence of divergent validity was obtained in relation to self-esteem and depressive symptoms. The Brazilian version of FMS also presented adequate values for internal consistency and 2-week test-retest reliability. These findings support the Brazilian version of the FMS as a useful tool for investigating muscularity-related aspects of body image and body change behaviors that are increasingly a source of concern for women.

     

Performance of an Adapted Version of the Timed Up-and-Go Test in People with Cognitive Impairments

In clinical practice, older people with cognitive impairment may have difficulties to understand the instructions of the Timed Up-and-Go (TUGT) test and present a bad performance. The purpose of this study was to identify differences in the TUGT performance, in an adapted version, between older adults with preserved cognition (PC), mild cognitive impairment (MCI) and Alzheimer's disease (AD), and to identify the association between the adapted TUGT performance and cognition among groups. A cross-sectional study was conducted with 118 community-dwelling older adults divided in three groups: PC (n?=?40), MCI (n?=?40) and AD (n?=?38). The evaluation was composed by the adapted TUGT and cognitive assessment (Addenbrooke's Cognitive Examination and Frontal Assessment Battery). Only the cadence of TUGT presented significant difference between groups, specifically between AD versus MCI and PC groups. The main correlations were found between time of TUGT with fluency domain and global cognitive function, especially in the AD Group. The findings contribute to the understanding of how cognition interferes on functional mobility in older people with MCI and AD. The adapted TUGT is easy to perform in clinical practice and can be useful when assessing mobility in people with cognitive impairment.     

Trait emotional intelligence and disposition for forgiveness

The association of trait emotional intelligence with a disposition for forgiveness was explored. In addition, the relationship between emotional intelligence and affect was also examined. A sample of 268 Portuguese students completed measures of trait emotional intelligence, disposition to forgive, and affect. Results demonstrated that trait emotional intelligence scores were negatively associated with lasting resentment and negative affect and positively associated with positive affect.     

Psychometric Properties of the Mental Health Continuum-Short Form: A Study of Portuguese Speaking Children/Youths

The development of measures of children and adolescents’ subjective well-being is crucial to the conceptualization and evaluation of positive mental health. The aim of this study was to investigate the factorial structure and invariance of the Mental Health Continuum-Short Form (MHC-SF—adolescents) across children and youths. Participants were from two different samples: 208 elementary school children (sample 1) and 216 middle school youths (sample 2). Results confirmed the three-dimensional structure of subjective well-being in both samples. The three sub-scales of the MHCSF yielded high internal consistency and results from the HTMT85 indicated discriminant validity. Measurement invariance testing across three different age groups (7–8, 9–10 and 11–14 years) confirmed the full metric and approximate scalar invariance of the MHC-SF. Full scalar invariance was achieved across gender. The study also compared the latent means for mental well-being in the three age groups, and found that the younger groups showed significantly higher levels of wellbeing. The present research study strongly suggests that the MHC-SF (adolescents) is an appropriate instrument to measure the positive mental health and well-being of children and pre-adolescents as multidimensional construct.     

Early control of reaching: effects of experience and body orientation

Although research suggests that experience may be a better indicator of the acquisition of certain abilities by infants than age, little work addresses this issue in the development of reaching movements in particular. This longitudinal study fills this gap by verifying the effect of practice time on more- and less-skilled reachers of the same age group in different body orientations. Less- (n=6) and more-skilled (n=4) reachers were evaluated at the acquisition of reaching and again after 1 month of spontaneous practice. Kinematic analyses examined 3D wrist motion during reaching trials in supine (0 degrees ), reclined (45 degrees ) and seated (70 degrees ) orientations. The results indicated that skill level was a relevant factor in dealing with gravitational constraints imposed by different body orientations. Time of practice affected the way less- and more-skilled reachers explored and adapted the kinematic parameters of reaching to constraints imposed by body orientations. These findings suggest that not only age, but also experience and body orientations are important constraints that should be taken into account when examining infant reaching development.     

Behavioral orientations and peer-contact patterns of relationally aggressive girls

The present study was designed to assess the behavioral orientations and peer-contact patterns of relationally aggressive girls. Based on teachers' assessments of relational aggression, 16 preschool girls were assigned to either a relationally aggressive group or a nonaggressive group and then observed in a free play setting. Several aspects of their interactive behaviors, e.g., cooperative play and social conversation, and noninteractive behaviors, e.g., solitary play and transition, were observed. Analysis indicated the relationally aggressive group spent more time engaged in social conversation and transition and less time in cooperative play than did the nonaggressive group. Further, findings indicated that the relationally aggressive group spent more time with one particular peer than did the nonaggressive group.
