When an assessment or test gathers psychological information about an individual without their knowledge or informed consent, it raises the ethical issue of invasion of privacy. This consideration requires professionals to ensure that individuals are aware of and have agreed to the assessment process.

The psychoanalytic orientation in group counseling, rooted in Freud’s theory, places strong emphasis on the influence of early childhood experiences (the past), unconscious motives, anxiety, and resistance to change. “Psychoanalytic groups focus on uncovering unconscious conflicts, past experiences, and the dynamics of resistance and anxiety.”

Manipulation of the independent variable is what distinguishes experimental research from non-experimental and quasi-experimental designs. In true experimental research, the researcher deliberately manipulates the independent variable to observe its effect on the dependent variable, allowing for the determination of cause-and-effect relationships.

The deficiency model proposes that cultural or ethnic differences are the result of social and economic deprivation or lack of opportunity, rather than inherent characteristics. This perspective views disparities as stemming from systemic inequality. “The deficiency model attributes group differences to environmental deprivation, particularly lack of access to social and economic resources.”

The mum effect refers to the tendency to withhold or soften the delivery of unpleasant or bad news. In counseling, this can occur when a counselor avoids giving clients information that is necessary but potentially upsetting, even though disclosure would be in the client's best interest.

The trait and factor theory is the oldest and most established career guidance theory, developed in the early 20th century by Frank Parsons. This approach is based on the idea that individuals have unique traits and that occupations require specific factors. Effective career guidance matches personal traits to job factors, making it the foundation for many subsequent career theories.

According to Kenneth Keniston, "youth" is a distinct period between adolescence and adulthood characterized by extended economic and personal temporariness. During this time, individuals are often not fully independent and may be exploring different roles before assuming adult responsibilities.

Formative evaluation is designed to collect information that can be used to improve a program while it is still ongoing. Descriptive data on client characteristics and needs are crucial for making adjustments in recruitment and group structure, and ensuring the group is meeting the needs of its target population. Summative evaluation, in contrast, would use outcome data (such as recidivism or graduation rates) after the program has been implemented.
