Summary
The K6 scale effectively measured serious emotional disturbance in Kentucky adolescents, revealing a 13.9% prevalence. This validated screening tool aids in timely mental health policy planning for youth.
Area of Science:
- Psychiatry
- Epidemiology
- Public Health
Background:
- Accurate psychiatric morbidity data is crucial for adolescent mental health policy.
- Clinically validated instruments are needed for effective regional planning.
- The K6 scale assesses serious emotional disturbance.
Purpose of the Study:
- To validate the K6 scale for measuring serious emotional disturbance in Kentucky adolescents.
- To determine the prevalence of serious emotional disturbance in this population.
- To identify correlates of serious emotional disturbance.
Main Methods:
- Factor analyses (principal axis, confirmatory) assessed the K6 scale's unidimensionality.
- A school-based sample of 108,736 Kentucky students participated.
- The K6 cutoff of 13 was used for screening and prevalence estimation.
Main Results:
- Factor analyses confirmed the K6 scale's 1-factor solution.
- The prevalence of serious emotional disturbance was 13.9% in Kentucky.
- Grade, gender, race/ethnicity, and family structure were significant predictors.
Conclusions:
- The K6 scale is a valid and reliable tool for assessing serious emotional disturbance in adolescents.
- The K6 is suitable for large epidemiologic surveys requiring timely administration.
- Findings support targeted mental health interventions for at-risk youth.

One-way ANOVA can be performed on three or more samples of unequal sizes. However, calculations get complicated when sample sizes are not always the same. So, while performing ANOVA with unequal samples size, the following equation is used:

02:01Group Design
9.3K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

01:15One-Way ANOVA: Equal Sample Sizes
3.2K
One-Way ANOVA can be performed on three or more samples with equal or unequal sample sizes. When one-way ANOVA is performed on two datasets with samples of equal sizes, it can be easily observed that the computed F statistic is highly sensitive to the sample mean.
Different sample means can result in different values for the variance estimate: variance between samples. This is because the variance between samples is calculated as the product of the sample size and the variance between the...

24.5K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

01:25Choosing Between z and t Distribution
2.9K
The z and the Student t distribution estimate the population mean using the sample mean and standard deviation. However, to decide which distribution to use for a calculation, one needs to determine the sample size, the nature of the distribution, and whether the population standard deviation is known. If the population standard deviation is known and the population is normally distributed, or if the sample size is greater than 30, the z distribution is preferred. The Student t distribution is...

Standardized test scores often follow a symmetric distribution that can be modeled with the normal distribution, a fundamental concept in statistics. This distribution is particularly useful for interpreting test performance fairly across populations, as it provides a mathematical framework for understanding variability and central tendency in large datasets.From Histogram to Frequency DistributionRaw test data are often displayed using histograms, where the height of each bar represents the...
