Parenting Styles, Anxiety and Depressive Symptoms in Child/Adolescent

OBJECTIVE

To analyse the possible direct and interactive associations of sex, age and parenting styles with symptoms of depression and anxiety.

METHODS

In this cross-sectional study, 710 students ranging from 8 to 13 years (mean age 10.8 years [ 0.75]), the most of them males (n = 422, 59.4%), completed three screening instruments: a parenting practices scale and two self-reports for evaluating anxiety and depressive symptoms. Two hierarchical multiple regression analyses were performed.

RESULTS

Authoritative (38.6%) and neglectful (38%) parenting styles were predominant. Symptoms of depression -F (3, 706) = 3.12, p = .03- and anxiety -F (3, 706) = 2.83, p = .4- differed by parenting styles. Students with a neglectful parenting style reported significant lower generalized anxiety symptoms than those whose parents used authoritative parenting.

CLINICAL IMPLICATIONS

Children ages 8 to 13 years-old with authoritative parenting style should be evaluated for possible presence of generalized anxiety symptoms.

General Health Questionnaire-12 validity in Colombia and factorial equivalence between clinical and nonclinical participants

The General Health Questionnaire - 12 (GHQ-12) is a widely used screening self-report for emotional disorders among adults. However, there is little evidence concerning the validity of the GHQ-12 in Colombia and its factorial invariance between nonclinical and clinical samples. Accordingly, the current study aims to explore the GHQ-12 validity in Colombian nonclinical and clinical samples. The GHQ-12 was administered to a total of 1641 participants, including a sample of undergraduates, one of general population, and a clinical sample. The internal consistency of the GHQ-12 across samples was good (overall alpha of .90). The one-factor model showed a good fit to the data and was considered theoretically more coherent than the two-factor model with positive and negative items loading in separate factors. Metric and scalar invariance were observed across nonclinical and clinical samples. The GHQ-12 scores were strongly and positively related to emotional symptoms and experiential avoidance, and negatively related to life satisfaction. According to the receiver operating characteristic (ROC) curves, a threshold score of 11/12 was optimal to identify emotional disorders. In conclusion, the GHQ-12 is a valid screening self-report in Colombia that provides scores that can be compared across clinical and nonclinical participants.

Colombian Creole horse breeds: Same origin but different diversity

In order to understand the genetic ancestry and mitochondrial DNA (mtDNA) diversity of current Colombian horse breeds we sequenced a 364-bp fragment of the mitocondrial DNA D-loop in 116 animals belonging to five Spanish horse breeds and the Colombian Paso Fino and Colombian Creole cattle horse breeds. Among Colombian horse breeds, haplogroup D had the highest frequency (53%), followed by haplogroups A (19%), C (8%) and F (6%). The higher frequency of haplogroup D in Colombian horse breeds supports the theory of an ancestral Iberian origin for these breeds. These results also indicate that different selective pressures among the Colombian breeds could explain the relatively higher genetic diversity found in the Colombian Creole cattle horse when compared with the Colombian Paso Fino.
