Participation in daily activities is essential for the development of the physical, emotional, social-psychological skills, and is also deemed as the major goal of rehabilitation after brain damage. Participation patterns are entirely dependent on the culture; therefore, perhaps it is not sensible to generalize the results of the studies undertaken in one culture to other cultures. This study, as a pilot study, was conducted to assess the children’s participation in activities outside school in Tehran. The mean of the overall diversity of participation for the children with cerebral palsy (23.066) was greater than that reported on Engel-Yeger (2009) (
16) and Longo et al. (2013) (
22) studies undertaken in Israel and Spain. The differences in the diversity of participation were found to be significant between the two groups in all measures except for the recreational activities. This finding supports the results observed in the comparative study of Engel-Yeger (2009) (
16) on the children with cerebral palsy and their normal peers all aged 12 to 16 years. It was also aligned with the finding of Brown and Gordon (1987) (
9) study in children with physical disabilities. However, in terms of skill activities, the finding was not in line with the findings of Engel-Yeger (2009) (
20) study. Regarding the intensity of participation, the differences between the CP and NP groups in all types of activities, except for recreational activities, were also statistically significant, which corresponds with the results of the previous studies (
7,
16). Palisano et al. (2011) (
23) suggest that in children with cerebral palsy, greater physical activity is associated with a higher intensity of participation (
23).The low intensity of participation influences the body fitness, the skill development, the probability of acceptance by their normal peers, the development of the friendly relationships, and the feelings about oneself (
7). The children with cerebral palsy had the most diversity and intensity of participation in the recreational activities and the least diversity and intensity of participation in the skill activity. Investigating the participation of the children with cerebral palsy, Majnemer et al. (2008) (
13) and Longo et al. (2013) (
22) concluded that the participation of the children with cerebral palsy in the physical and skill-based activities was less than that in other leisure and recreational activities (
13,
22). Law et al. (2006) (
8) study in children with physical disabilities, aged 8 to 14 years, and many other studies also found similar results (
7, 8,
24). Due to the fact that a majority of physical and skill-based activities is required to be done outside and needs physical abilities, the children with cerebral palsy seem to have less opportunity to participate in such activities especially due to their physical as well as access problems. Their normal peers also indicated the most diversity of participation in recreational activities and the least diversity in skill activities; however, the normal peers had the most intensity of participation in the self-help activities and the least intensity in the skill activities. Some of the reasons of the low intensity of participation of the children with cerebral palsy can be found in the problems related to handling and transfer by their parents and the cost of these children’s participation in the leisure activities, while this money could be expended on their treatment. In comparison with the normal children, the children with cerebral palsy preferred to perform the skill and overall activities by themselves, which can be owing to the fact that their normal peers would rather cooperate with their friends in performing these activities; while the physical restrictions of the children with CP may impede them from doing various activities in different environments. Therefore, they perform the activities in the environments which are adapted based on their disabilities such as home and schools (
8,
16). Nonetheless, considering this aspect (whom dimension), no significant difference was found between the two groups regarding the recreational, actively physical, social, and self-help activities. Participating in these activities is of paramount importance for the children with cerebral palsy, which means that they recognize themselves as part of the family and society; otherwise, they, in comparison with their normal peers, participate less in the activities outside school. This can be due to the fact that the children with cerebral palsy would rather perform the activities at home where parents can assist them more. On the contrary, the peers without cerebral palsy are more independent and are able to spend part of their time outside the house. Children with disabilities and their families encounter the contradictions of the development of the emotional independence and an independent identity, while these children are still physically dependent on their parents or caregivers (
25).
The main effect of gender and that of the interaction of groups and genders were not significant in any of the test parameters, which is in line with the results reported in some previous studies. However, considering the diversity of participation, the findings support the results of King et al. (2006) (
21) study in which they observed that the diversity of participation was only greater in the self-help activities for the girls with physical disabilities than for physically disabled boys. According to the results of various studies, it seems that gender and culture can affect the type of the activities selected by them and the activity pattern. Gender is deemed as an important factor in the participation, especially in performing the leisure activities (
26,
27). Investigating normal children in two different cultures, Engel-Yeger et al. (2007) concluded that there was a significant interaction between culture and gender (
20).
Participation in out-of-school time plays an important role in the health, welfare, and development of children. The participation of the children with physical disabilities in daily activities is an influential factor in gaining independence in adulthood (
28). Participation as a key purpose of rehabilitation programs has grabbed enormous attention with the intention of helping children and families in coping with the challenges they face (
29). Levels of participation in the life roles may be modified due to the functional limitations and environmental and personal factors (
30). The main goal of rehabilitation for school-age children with cerebral palsy is to enhance independence in self- care, mobility, and productivity (
30). Increasing participation can be considered as the ultimate goal of rehabilitation; hence, measuring the level of participation is essential for evaluating the effectiveness of rehabilitation programs (
31).
Based on the results, it can be declared that the cerebral palsy can affect the diversity and intensity of the children’s participation. Regarding the great importance of participation in the purposeful childhood activities and its impact on health and growth of children, the understanding of the participation patterns of the children with cerebral palsy and without disabilities can pave the way for the occupational therapists and families to design activities and treatments tailored to the needs of the children and promote their health and participation.
