Chapter 2 Notes: Medical and Psychological Theories, Frames of Reference and Models in Mental Health

Introduction: The role of theory, frames of reference, and models in OT mental health

• Theories provide guidance on what to do with a client in a given situation.

• A theory is a way of looking at how the mind works; it offers a set of principles and concepts to explain behavior and aspects of mental health.

• Frames of reference: the profession’s view of a particular domain as a mechanism to help a client change.

• Models: synthesize philosophical bases and theoretical concepts into a coherent approach; can be based on multiple theories; help organize thinking about a client’s performance.

Psychoanalytic Theory: Model of Object Relations

• Core idea: mental health and disorders are influenced by our relations with objects in our environment.

• Key components in personality: the id, ego, and superego.

• Defense mechanisms: important for OTPs to speculate on why a client behaves as they do and to tailor responses; largely unconscious according to Freud.

• Object relations focus: symbols are used as keys to unconscious conflicts; therapists may use symbols expressed by clients in arts, crafts, and everyday activities.

• Practical tools: see Table $2.1 (page 27) for defense mechanisms; see Table 2.2 (pages 28–30) for examples of craft projects OTPs can use therapeutically to help clients express emotions and manage feelings.

Developmental Theory

• Core idea: development involves maturing through a fixed sequence of stages; mastery of developmental tasks provides a foundation for later growth.

• Developmental lag occurs when behavior does not match what is expected for a person’s age, potentially due to physical illness, poverty, malnutrition, trauma, or emotional/social deprivation.

• Erikson’s Eight Stages of Psychosocial Development: see Table 2.4 (page 33).

Behavioral Theories

• Central concept: behavior is learned through interactions with the environment.

• Learning mechanism: adaptive behaviors are rewarded; maladaptive behaviors are punished, guiding the person toward more mature and responsible functioning.

• Mental disorders may involve abnormal behaviors due to lack of reinforcement for adaptive behaviors or absence of pleasurable consequences.

• Therapeutic techniques: OTPs use a variety of behaviorally based methods.

• Action–consequence approach: change a person’s behavior by altering the consequences of the behavior.

• Reinforcement: selecting reinforcement and choosing between intermittent or continuous schedules (see Table 2.6 (page 37) for steps of developing a behavioral treatment plan).

• Key procedures:

  • Shaping: gradual progression toward a target behavior through small steps or successive approximations.

  • Chaining: teaching one step at a time.

  • Systematic desensitization: reducing fear via gradual exposure.

Cognitive Behavioral Theoretical Continuum

• Core idea: behavior is influenced by what we think and believe; maladaptive cognition leads to maladaptive behavior.

• Automatic thoughts: negative cognitions that occur without conscious awareness or challenge.

• Integrated intervention: targets both cognition and behavior; focuses on the relationship between thoughts and actions.

• Cognitive techniques: challenge and modify negative thoughts and underlying assumptions.

• Behavioral techniques: examine consequences of behaviors and evaluate effectiveness.

• Homework: clients engage in reading, graded tasks, and activity scheduling; practice outside sessions.

• Cognitive rehearsal: clients imagine performing each successive step of a task to attend to details that might lead to failure if overlooked.

• Self-monitoring: clients record negative cognitions and related events to identify frequency and the sequence of thoughts, feelings, and behaviors.

• Reattribution: challenges the belief that personal shortcomings cause negative external events; particularly helpful for depression.

• Practical guide: See steps 1–7 on page 40 to facilitate change in daily life using negative reinforcement.

Cognitive Enhancement Therapy (CET): A Neurodevelopmental Approach

• CET aims to improve cognitive abilities, processing speed, and social cognition.

• Recognized as an evidence-based intervention technique.

• CET is based on traumatic brain injury (TBI) rehabilitation principles and neuroplasticity; described in a 12-month study with demonstrated benefits of CET training.

• The CET framework is holistic and integrates cognitive thinking skills with social interaction skills; socialization is a key component.

• Practical implications: CET bridges cognitive processing and real-world social functioning, enabling broader functional gains.

Client-Centered Humanistic Therapy

• Central tenet: humans have the potential to direct their own growth and development.

• Non-directive approach: therapists help clients become more aware of their feelings and the consequences of contemplated actions.

• Mental health problems arise when a person is not aware of their feelings and available choices.

• Therapeutic stance: clients can become more aware by experiencing and exploring feelings in the therapeutic relationship with an OTP.

• Core helping behaviors:

  • Unconditional positive regard: continuing to like the client regardless of actions.

  • Empathy and warmth in the client-therapist relationship.

• Interviewing techniques:

  • Open-ended questions to invite dialogue.

  • Minimal responses to encourage client speech (e.g., nodding, saying “go on”).

  • Reflection of feelings: articulating the client’s emotions to deepen awareness.

  • Paraphrasing: restating the client’s words with different wording.

  • Withholding judgment: avoid giving opinions about the client’s remarks or behaviors.

Neuroscience Theories

• Principle: use knowledge of the nervous system to guide treatment planning.

• Assumptions: normal function requires a normal brain structure, neurophysiology, and neurochemical balance; deviations may be linked to certain disorders (e.g., schizophrenia).

• Intervention implications: if brain deficits cause a disorder, interventions may target somatic conditions through pharmacotherapy, psychosurgery, and electroconvulsive therapy (ECT).

• OT approaches connected to neuroscience:

  • Lorna Jean King’s Sensory Integration approach for schizophrenia: using games and postural exercises to influence sensorimotor functioning and engage CNS pathways processing sensory information.

  • Allen’s perspective: precise definition of a person’s functional level and environment modification to support function.

  • Dunn and Westman: sensory processing evaluation for adults and adolescents with strategies to modify the environment to compensate for sensory differences.

Psychiatric Rehabilitation and Psychosocial Rehabilitation (PsyR)

• Focus: helping a person with a mental disorder function optimally in life situations.

• PsyR orientation is similar to OT in emphasizing present and future goals, development of skills/resources, and use of activities and environmental adaptations as the basis for intervention.

• Guiding principles: see bullet points on page 48 (summaries of PsyR principles).

• Rehabilitation process (three-stage):

  • Rehabilitation diagnosis.

  • Rehabilitation planning.

  • Rehabilitation intervention.

• Rehabilitation Readiness: Box 2.1 on page 50 outlines the 6 dimensions of rehabilitation readiness.

Explanatory Models from Other Cultures

• Rationale: different cultures may attribute emotional distress and abnormal behavior to distinct causes.

• Page 51 discusses cross-cultural considerations and explanations for distress.

• Box 2.2 (page 51) presents 3 examples of cultural concepts of distress.

Connections, Implications, and Practical Takeaways

• Integration of theories: OT practice often blends elements from psychoanalytic, developmental, behavioral, cognitive-behavioral, humanistic, and neuroscience perspectives to tailor interventions.

• Frames of reference guide which domain is emphasized (e.g., sensorimotor, cognitive, humanistic, or psychosocial approaches); models synthesize these ideas for practical application.

• Ethical considerations: respect for client autonomy (as in client-centered therapy); awareness of cultural concepts of distress; avoiding over-pathologizing normal responses across cultures.

• Real-world relevance: selection of interventions (e.g., CET for cognitive/social deficits; PsyR for community reintegration; sensory integration adaptations for daily living) improves functional outcomes.

• Numerical references to study materials: tables and boxes (e.g., Tables 2.1, 2.2, 2.4, 2.6 and Boxes 2.1, 2.2) and page numbers cited throughout are essential anchors for locating details in the original text.
