Effect of ecological walking training in sedentary elderly people: act on aging study.

PURPOSE OF THE STUDY: This study aims to investigate the effects of a walking program on aerobic endurance and function in a sample of sedentary elderly people. DESIGN AND METHODS: For this study, 126 sedentary individuals were recruited: 63 individuals (mean age = 74.1±6.0 years) for the control group and 63 (mean age = 72.0±4.5 years) for the intervention group. The intervention consisted of walking training including balance exercises and lower limb strength activities twice a week for 4 months. We collected baseline and post-test measurements of aerobic endurance, lower limb strength, and mobility. We also measured aerobic endurance at increments of 4, 8, and 12 weeks between the baseline and the post-test. We used analyses of covariance with baseline value, gender, age, and body mass index scores as covariates (p < . 05) and calculated the effect size for the effects of the intervention. The changeover time of aerobic endurance was also analyzed with the repeated analysis of variance (p < .05). RESULTS: The intervention group showed steady and significant improvements with respect to the 6-min walk (aerobic endurance) from 447.89 m (SD 73.87) to 561.51 m (SD 83.96), as well as the 30-s chair stand (lower limb strength) from 10 (SD 3) to 13 (SD 3) number of times and the Timed Up and Go Test (mobility) from 8.53 s (SD 2.86) to 7.13 s (SD 1.76) at the post-test, whereas the control group showed significant decrease in all measurements. IMPLICATION: These results underline that an ecological walking training program can be used to improve physical functioning among sedentary elderly people.

Adolescent non-suicidal self-injury: a cross-national study of community samples from Italy, the Netherlands and the United States.

This study examined rates and correlates of non-suicidal self-injury (NSSI) across three non-clinical adolescent samples from different countries. Surveys were administered to 1862 adolescents (M(age)=15.69, S.D.=0.87) from Italy (n=827), the Netherlands (n=675), and United States (n=360), including measures of NSSI, substance use, internal (i.e., depressive symptoms, loneliness), and interpersonal factors (i.e., peer victimization, peer preference). After controlling for socio-demographic differences, similar prevalence of NSSI was found across the three samples, with approximately 24% of the adolescents reporting at least one NSSI episode within the last year. Multivariate logistic regressions showed that adolescents' victimization and higher levels of depressive symptoms and family-related loneliness were associated concurrently with NSSI comparably in all three samples. However, multi-group analyses indicated that the association between NSSI and substance use varied significantly across samples, indicating that NSSI related more strongly to substance use (i.e., cigarette smoking and frequent marijuana use) in the sample from the United States rather than the samples from the Netherlands and Italy. Findings provide evidence of NSSI and suggest high similarities in rates and correlates across samples from different countries. Future research should further explore NSSI cross-nationally.

Elderly-technology interaction: accessibility and acceptability of technological devices promoting motor and cognitive training.

As the world population is ageing, studies on the socio-economic and health consequences are proliferating. Little has been done on the effectiveness and impact elderly may benefit from the use of technology in their everyday life. The pilot study, implemented within a funded project aimed at identifying sustainable actions to promote Seniors' quality of life, intended to investigate this kind of interaction in terms of accessibility and acceptability that senior citizen experience with technological devices promoting motor and cognitive training. In the hypothesis, interfaces and technological artifacts, that still take in little account the seniors' physical characteristics (e.g. physiological limitations in sight, hearing, movement) and cognitive processes (selective memory often driven by practical needs), can cause elderly to mistrust technology. Study participants were twenty over seventy-year-old people, who were observed and interviewed in context in a two-hour training session regarding the technological devices user experience. The results are presented with scenario-based techniques that help represent typologies of users in different use situations. Findings confirm the hypothesis, highlighting that elderly may accept technological artifacts when they perceive them as bringing benefits in terms of well-being and health.

Drinking motives and alcoholic beverage preferences among Italian adolescents.

Although drinking motives have been largely studied, research taking into account the Mediterranean drinking culture and focusing on motives specifically associated to adolescents' developmental tasks is lacking. For these reasons the study investigates drinking motives in a group of Italian adolescents and their relationships with drunkenness and high levels of alcohol consumption (wine, beer, spirits and alcopops). A self-report questionnaire on drinking motives and amount of alcohol use was administered to 784 adolescents, boys (46%) and girls, ages 15-19. Using confirmatory factor analysis and stepwise logistic regressions, we found that: 1) motives for drinking were coping, conformity, self-affirmation and experimentation-transgression; 2) coping motives were positively related to the high consumption of all alcoholic beverages and to drunkenness; 3) conformity motives were negatively related to high beer consumption and drunkenness, while experimentation-transgression motives were positively related to high alcopops consumption. Implications for prevention are discussed.

Family functioning's contributions to values and group participation in Italian late adolescents: a longitudinal study.

This longitudinal study aimed to investigate the contributions of family functioning (in terms of support and control) to the development of civic engagement in term of personal values (i.e., values related to health, school, religion, and disapproval of deviance) as well as participation in groups that pursue cultural, religious-volunteer, and sport goals. The study controlled for sociodemographic factors, such as parental level of education and integrity of the family. Two waves of data were collected among 175 Italian late adolescents at a one-year interval. Hierarchical regression analyses showed that the average level of parental support positively related to both health value and religion value; increased parental control positively related to health value and disapproval of deviance; and average levels of both parental support and control positively related to religious-volunteer group. However, increased parental support negatively related to participation in a cultural group. The discussion focused on the important role of the family in current Italian society for youth socialization in regard to civic engagement.

Similarity in depressive symptoms in adolescents' friendship dyads: selection or socialization?

This study examined friendship selection and socialization as mechanisms explaining similarity in depressive symptoms in adolescent same-gender best friend dyads. The sample consisted of 1,752 adolescents (51% male) ages 12-16 years (M = 13.77, SD = 0.73) forming 487 friend dyads and 389 nonfriend dyads (the nonfriend dyads served as a comparison group). To test our hypothesis, we applied a multigroup actor-partner interdependence model to 3 friendship types that started and ended at different time points during the 2 waves of data collection. Results showed that adolescents reported levels of depressive symptoms at follow-up that were similar to those of their best friends. Socialization processes explained the increase in similarity exclusively in female dyads, whereas no evidence for friendship selection emerged for either male or female dyads. Additional analyses revealed that similarity between friends was particularly evident in the actual best friend dyads (i.e., true best friends), in which evidence for socialization processes emerged for both female and male friend dyads. Findings highlight the importance of examining friendship relations as a potential context for the development of depressive symptoms.

The role of inhibitory control in children's cooperative behaviors during a structured puzzle task.

This study examined the role of inhibitory control (measured by Stroop interference) in children's cooperative behaviors during a structured puzzle task. The sample consisted of 250 8-, 10-, and 12-year-olds (117 girls and 133 boys) attending classrooms in three primary schools in Northern Italy. Children individually completed an elaborated Stroop task, were paired with classmates into 125 dyads, and were observed during a 10-min puzzle task. Results confirmed that interaction partners exhibited similar levels of cooperative behaviors, and the cooperative behaviors of children predicted changes in the cooperative behaviors of their partners throughout the puzzle task. Cooperative behaviors of each interaction partner were predicted by the child's own inhibitory control as well as the inhibitory control of the partner. Findings are discussed within a developmental contextual framework.

Results of an Italian school-based expressive writing intervention trial focused on peer problems.

This study investigated the effectiveness of an expressive writing intervention in a sample of Italian early adolescents on internalizing and post-traumatic stress symptoms and coping strategies. Participants were 153 Italian adolescents (48% male), attending 7th grade (M=12.24 yrs, SD=0.47). Youth were randomly assigned either to write about personal emotional events related to problems they recently experienced with peers, or trivial topics. Data were collected before and 2 months following the intervention. Analyses revealed no overall intervention effects on symptoms. However, level of peer victimization moderated the effects of the intervention on coping strategies, such that victimized youth in the intervention showed increases in cognitive restructuring and avoidance coping, relative to other groups. Thus, expressive writing affected coping strategies but not internalizing problems in our early adolescent sample.

Meanings of sexual intercourse for Italian adolescents.

The goal of the present study was to investigate meanings of sexual intercourse in adolescence, and the relationships between meanings, gender, age, and sexual behaviors. Subjects were 201 Italian adolescents (107 boys and 94 girls), aged 14-19 (M=17.44, SD=1.65). Participants completed a battery of questionnaires on meanings of sex, sexual activity and other risk behaviors. Using confirmatory factor analyses and ANOVAs, we found: (1) four dimensions of meanings of sexual intercourse: negative social, personal, transgressional, and positive social meanings; (2) females scored much lower on all four dimensions; (3) negative social meanings were related to a lack of protection in sexual intercourse, whereas trangressional meanings were related to lack of protection at the first sexual intercourse only. Our findings suggest a similarity between meanings of sexual intercourse and meanings of others risk behaviors, including smoking. This similarity should be taken into account in prevention against health-risk behaviors in youth.

Parenting and adolescent well-being in two European countries.

The main and interactive effects of parental behavioral control and parental support on adolescent adjustment were examined with students ages 15-19 in Italy (N = 391, 59.1% male) and The Netherlands (N = 373, 45.3% male). In general, parental support was associated with better adjustment and parental control was associated with worse adjustment. However, parental control as well as age and sex moderated the effects of parental support on psychological discomfort and expectations of future success. Positive self-perceptions were less well predicted. Further, there were more moderated effects in the Dutch sample than in the Italian sample. Generalizability of the contributions of parenting behavior to adolescent adjustment outside of a North American context is discussed.

Executive inhibitory control and cooperative behavior during early school years: a follow-up study.

Several links between aspects of executive functioning and the development of social competence have been established. The present study investigates the relation between executive inhibitory control and cooperative/non-cooperative behavior, in an ecological setting, and from a longitudinal perspective. Elementary school children (n=195) of three age groups (7, 9, 11 years, initially) were measured at two consecutive time points, at a one-year interval, with tasks tapping executive inhibitory control (the Stroop test), and social competence (a collaborative puzzle solving task). Executive inhibition was identified as the most influential stable predictor only in the case of non-cooperative behavior and presented strong concurrent relations with both cooperative and non-cooperative behavior at follow-up, even when controlling for previous level of the same behavior. The findings imply the need to consider the important role of executive inhibitory processes in multifactorial models of social competence development and in the refinement of present interventions.

Dating, sexual activity, and well-being in Italian adolescents.

Associations among dating, sexual activity, gender, and adjustment were investigated in 2,273 Italian adolescents (54% female, ages 14 to 19 years) attending public high schools. After controlling for age and type of school attended, both being in a dating relationship and being male were associated with less alienation, more positive views of the self, and higher general expectations for success. Sexual activity interacted with both gender and dating status in predicting feelings of depression. For boys, there were no differences between youth who were sexually active and youth who were not; however, sexually active girls had higher levels of depressive symptoms than girls who were not sexually active. Among youth who were not sexually active, there were small differences between daters and nondaters; among sexually active youth, daters had lower levels of depression than nondaters. Gender differences in adolescents' experience of dating and sexual relationships and implications for adjustment are discussed.
