Self-Report Tests of Personality01:22

Self-Report Tests of Personality

488
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Reliability and Validity01:29

Reliability and Validity

13.3K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Measures of Intelligence01:29

Measures of Intelligence

7.9K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Longitudinal Research02:20

Longitudinal Research

12.6K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Testing a Claim about Population Proportion01:24

Testing a Claim about Population Proportion

3.5K
A complete procedure for testing a claim about a population proportion is provided here.
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Comparing Experimental Results: Student's t-Test01:09

Comparing Experimental Results: Student's t-Test

2.4K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

Summary

The Evaluation in Ayres Sensory Integration (EASI) Praxis tests show good internal consistency and are sensitive to developmental changes in children aged 6 to 12. This supports their use in assessing praxis ability through early adolescence.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Occupational Therapy

Background:

  • Ayres Sensory Integration® is an evidence-based practice requiring thorough assessment.
  • The Evaluation in Ayres Sensory Integration (EASI) is designed for assessment, necessitating psychometric validation.
  • Previous research highlighted the need for psychometric data on EASI's validity and reliability.

Purpose of the Study:

  • To evaluate the internal consistency of four EASI Praxis tests.
  • To determine the validity of EASI Praxis tests as developmental measures.
  • To assess the sensitivity of EASI Praxis tests to developmental changes in children and adolescents.

Main Methods:

  • Cross-sectional developmental study design.
  • Participants included 234 typically developing children and young adolescents aged 6 to 12 years.
  • Analysis involved Cronbach's α, Pearson correlation coefficients, and one-way ANOVA for internal consistency and developmental trends.

Main Results:

  • All four EASI Praxis tests demonstrated moderate to high internal consistency.
  • Significant correlations between age and praxis scores confirmed the tests' sensitivity to developmental changes.
  • Praxis ability showed continued development into early adolescence.

Conclusions:

  • Occupational therapists can rely on the internal consistency and developmental sensitivity of EASI Praxis scores for ages 6 to 12.
  • The findings support the continued development of praxis into early adolescence.
  • EASI Praxis tests can inform assessment and intervention for praxis ability in this age group.
