Abstract:
Urbanization, industrialization, globalization, changing cultural trends and the social 
metric shift of the late 20th century has led to profound change in family structure 
worldwide over the last five decades. The trends indicate that the number of children 
living in two parent families is declining sharply. On the other hand, the trend shows 
that the number of children living in single parent families is on the increase. These 
trends in the family structure have major implications on the psychosocial aspects and 
academic performance of children. Increase in psychosocial and schooling problems 
such as drug abuse, school arson and strikes, bullying, early sexual debut, teen 
pregnancy, suicidal thoughts and suicide, and examination malpractices among 
secondary school students is becoming a major challenge in Kenya. The purpose of 
this study was to investigate the influence of family structure on students’ 
psychosocial aspects and academic performance in public secondary schools in 
Kiambu County, Kenya. The study was guided by four objectives namely: to find out 
the influence of family structure on students’ self-acceptance; to establish the
influence of family structure on students’ interpersonal relationships; to determine the
influence of family structure on students’ social integration and to establish the 
influence of family structure on students’ academic performance in public secondary 
schools in Kiambu County, Kenya. The study was anchored on Maslow’s Hierarchy
of needs and Social cognitive theories. Descriptive research design was adopted for 
the study. Purposive sampling was used to select Kiambu County and form four 
students while proportionate stratified sampling technique was used to select 30 
schools from the 274 public secondary schools in Kiambu County. Random sampling 
technique was employed to select the 385 students from the selected schools. Self administered student’s questionnaire containing sub- scales on self-acceptance, 
interpersonal relationships and social integration and the KCSE national examination 
results of 2017 were used for data collection. Reliability of the questionnaire was 
tested by computing Cronbach alpha coefficient. Collected data was analyzed using 
both descriptive and inferential statistics in line with the study objectives. The null 
hypotheses were tested using Kruskal Wallis H test (one-way ANOVA on ranks) test 
at 0.05 significance level. Statistical Package for Social Sciences (SPSS) aided the 
data analysis. The findings indicated statistically significant influence of family 
structure on student’s self-acceptance,

significant influence of family structure on students’ interpersonal relationships,

(1) = 2.02, p = .155; social integration, 2(1) = 0.028, p =0.866 and academic 
performance, 2(1) = 0.898, p = 0.343 was found. A major implication and 
recommendation of the study was that all stakeholders in education should validate 
and foster the development self-acceptance, interpersonal relationships, social 
integration and academic performance among students. Warm, nurturing, structured 
and authoritative school environment to be provided for healthy development of 
students’ psychosocial aspects and academic performance. Further research should
also consider other family structure factors such as family disposition, family 
relationships, gender of single parent, parental social-economic status, duration in the 
family structure and their influence on psychosocial aspects and academic 
performance of the students. The major beneficiaries of this study are students, 
teachers, parents and policy makers.
