    Insights

    A new observational tool, the Cohen-Mansfield Agitation Inventory-Observational (CMAI-O), accurately measures agitation in people with dementia. This validated instrument offers a reliable alternative to proxy-reported scales, enhancing research in care homes.

    Area of Science:

    • Gerontology
    • Psychiatry
    • Clinical Psychology

    Background:

    • Agitation is a common behavior in individuals with dementia.
    • The Cohen-Mansfield Agitation Inventory (CMAI) is a widely used proxy-reported scale.
    • Proxy reporting may introduce bias and accuracy issues in agitation assessments.

    Purpose of the Study:

    • To develop and validate an observational version of the CMAI (CMAI-O).
    • To assess the validity of CMAI-O as an alternative or complementary measure of agitation.
    • To address limitations of proxy-reported agitation measures in dementia research.

    Main Methods:

    • Development and validation of the CMAI-O.
    • Observational measures (CMAI-O and PAS) completed by independent researchers.
    • Data collected from 726 residents with dementia across 50 care homes in England.

    Main Results:

    • CMAI-O demonstrated adequate internal consistency (α = .61).
    • Strong criterion validity with the PAS (r = .79, p < .001).
    • Showed incremental and discriminant validity in predicting quality of life and differentiating from apathy.

    Conclusions:

    • The CMAI-O is a promising research tool for independent agitation measurement in dementia.
    • It can be used alongside the CMAI for a more robust understanding of agitation.
    • Facilitates objective assessment of agitation in care home residents.

    Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

    The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
    Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

    Naturalistic Observations

    If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

    Reliability and Validity01:29

    Reliability and Validity

    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.

    Data Validation

    Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
    Nursing assessment guides are generally based on holistic models rather than medical...

    Data Validation

    Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
    Key parameters for method validation include:

    Actor-Observer Effect01:23

    Actor-Observer Effect

    The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...
