Background:
The Strengths and Difficulties Questionnaire (SDQ) is a screening questionnaire that measures children's emotional and behavioural problems. This study examines the reliability and validity of the Malay parent-report version of the SDQ.
Methods:
The Malay adult-report version of the SDQ was administered to 495 parents and 432 teachers, respectively. At the same time, a newly translated Malay child-report version of the SDQ was also administered to 150 children aged 13 to 14 years old in this community study. W e measured internal reliability using Cronbach's Alpha for all reported data. Construct validity of the parent-report data was assessed using factor analysis. Confirmatory Factor Analysis (CFA) was also subsequently perform on parent-report data to explain the model fit indices of this questionnaire.
Result:
Cronbach's Alpha was acceptable for all parent, teacher and child-report data with values of 0.74, 0.77 and 0.78, respectively. Factor analysis of the parent's report showed a five-factor solution, which was consistent with other psychometric evaluations of the SDQ in other languages. CFA showed good model fit of the original five factor model which consists of Emotional, Conduct, Hyperactivity, Peer problem and Pro-social scale.
Conclusion:
This study shows that the psychometric properties of the Malay parent-report version of the SDQ were similar to other parent-report version of the SDQ questionnaires in other languages, although cross-cultural differences may still exist.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.

03:05Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
