Summary
Persistent Complex Bereavement Disorder (PCBD) symptoms uniquely impact fear of loss, sleep, and social functioning in bereaved students. These findings support the clinical use of the PCBD diagnosis.
Area of Science:
- Psychology
- Clinical Psychology
- Psychiatry
Background:
- Persistent Complex Bereavement Disorder (PCBD) is a proposed diagnosis.
- Understanding its unique impact on functioning is crucial for clinical utility.
Purpose of the Study:
- To examine the incremental validity of PCBD symptoms.
- To determine if PCBD symptoms explain unique variance in life impairment beyond other common psychological distress symptoms.
Main Methods:
- An online survey was administered to 255 bereaved college students.
- Hierarchical multiple regression analyses were used to assess unique variance explained by PCBD symptoms.
Main Results:
- PCBD symptoms significantly predicted unique variance in fear of future losses, sleep impairment, and work/social impairment.
- PCBD symptoms did not significantly predict loneliness.
Conclusions:
- PCBD symptoms demonstrate incremental validity in specific domains of impairment.
- Findings support the validity and clinical utility of the DSM-5's PCBD construct.

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

01:29Reliability and Validity
13.9K
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.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...
