Families of children on the autism spectrum: experience of daily life and impact of parent education

Information and support for families of children on the autism spectrum is limited in south-east Europe. A three-year project, Equity and Social Inclusion Through Positive Parenting (ESIPP), was established to develop and provide parent education (PE) in autism for families in Croatia, Cyprus and North Macedonia. This paper presents findings from Croatia regarding family life and the impact of PE. Data were collected via pre- and post-PE questionnaires and semi-structured interviews. Participants discussed the impact of autism on family life, the difficulty of obtaining a diagnosis, the importance of family support (and varying experience of formal support), common experiences of stigma and social exclusion and concerns for the future. The value and benefit of PE is identified, and recognition of its impact within Croatia has ensured its ongoing provision.     

The effect of potential fall distance on hormonal response in rock climbing

The aim of this study was to examine the effect of alterations in potential lead fall distance on the hormonal responses of rock climbers. Nine advanced female climbers completed two routes while clipping all (PRO-all) or half (PRO-½) of the fixed points of protection. Venous blood samples were analysed for total catecholamines, noradrenaline (norepinephrine), adrenaline (epinephrine), dopamine, lactate, cortisol and serotonin. Differences between the two conditions pre, immediately post and 15 min post climbing were assessed using a 2 × 3 repeated measures ANOVA. All hormones and blood lactate concentrations increased significantly (P < 0.05) immediately post climb, except for cortisol. Peak cortisol concentrations did not occur until 15 min post ascent. Further, significant interactions between climbing and clipping conditions were found for total catecholamines (890% of basal concentration in PRO-½ vs. 568% in PRO-all), noradrenaline (794% vs. 532%) and dopamine (500% vs. 210%). There were no significant interactions for adrenaline (1920% vs. 1045%), serotonin (150% vs. 127%) or lactate (329% vs. 279%). The study showed a greater catecholamine response with an increase in potential lead fall distance. The most pronounced increases seen in catecholamine concentration were reported for dopamine and noradrenaline.
