NLE Foundations of Psychiatric & Mental Health Nursing — Foundations of Mental Health & Psychiatric NursingSummary

Mental health is a state of emotional, psychological, and social well-being in which a person realises their own abilities, copes with normal stresses of life, works productively, and contributes to the community (WHO definition). It is NOT merely the absence of mental illness. Characteristics of a mentally healthy person include a positive self-concept, capacity for satisfying interpersonal relationships, autonomy, accurate perception of reality, environmental mastery, and ability to adapt to change. In the Philippine setting, this includes strong family relationships and spiritual connectedness.

Mental illness refers to clinically significant disturbances in cognition, emotional regulation, or behaviour that cause distress or impairment in functioning. Mental health and illness exist on a continuum; individuals move along this continuum in response to stressors, available resources, and personal coping capacity. The same individual may experience periods of better and worse mental health depending on life circumstances, support systems, and biological factors.

Mental health status is determined by the interplay of three factor domains: (1) Biological—genetics, neurochemistry (imbalances in dopamine, serotonin, norepinephrine, GABA), physical health, nutrition, sleep, and exercise; (2) Psychological—temperament, self-concept, past experiences, coping skills, trauma history, and stress response patterns; (3) Sociocultural—family structure, poverty, education level, cultural beliefs, spirituality, social support networks, and discrimination. In the Philippines specifically, strong extended family structures and religiosity are protective factors, while stigma (expressing symptoms as *baliw* or spiritual possession) remains a significant barrier to help-seeking and treatment adherence.

Sigmund Freud conceptualised personality as organised into three interacting structures: (1) The Id—present from birth, entirely unconscious, operates on the pleasure principle demanding immediate gratification of instinctual drives (the 'I want it now' component); (2) The Ego—develops in infancy, largely conscious, operates on the reality principle, mediates between id demands, superego constraints, and external reality; serves as the executive and seat of defence mechanisms; (3) The Superego—develops around ages 3–6, represents the moral component or conscience, incorporates values and standards of parents and society, strives for perfection, produces guilt when violated. Freud also described levels of awareness: conscious (current awareness), preconscious (retrievable with effort), and unconscious (repressed material outside awareness that drives behaviour).

Erik Erikson expanded Freud's theory across the entire lifespan, describing eight stages, each characterised by a core psychosocial conflict that must be resolved for healthy development. The stages are: Infancy (0–18 months, Trust vs. Mistrust, virtue of Hope); Toddlerhood (18 months–3 years, Autonomy vs. Shame/Doubt, Will); Preschool (3–6 years, Initiative vs. Guilt, Purpose); School Age (6–12 years, Industry vs. Inferiority, Competence); Adolescence (12–20 years, Identity vs. Role Confusion, Fidelity); Young Adulthood (20–40 years, Intimacy vs. Isolation, Love); Middle Adulthood (40–65 years, Generativity vs. Stagnation, Care); Older Adulthood (65+ years, Ego Integrity vs. Despair, Wisdom). Successful resolution of each stage builds the foundation for the next; unresolved conflicts can lead to maladaptive behaviours or emotional difficulties.

Defence mechanisms are unconscious strategies the ego employs to protect itself from anxiety and resolve internal conflict. They become maladaptive only when overused or when they replace healthy problem-solving. Key mechanisms include: Repression (involuntary blocking of painful thoughts; cornerstone mechanism), Suppression (the ONLY conscious mechanism; deliberately postponing a worry), Denial (refusing to accept painful reality), Projection (attributing one's own unacceptable feelings to another), Displacement (transferring feelings from threatening to safer target), Rationalisation (offering acceptable reasons to justify behaviour), Reaction Formation (acting opposite to true feelings), Regression (returning to earlier developmental behaviour under stress), Sublimation (channelling unacceptable impulses into socially acceptable activity; considered most mature), Undoing (performing an act to cancel a previous one), Compensation (covering weakness by excelling elsewhere), Identification (modelling oneself on an admired person), and Conversion (channelling emotional conflict into physical symptom with no organic cause).

The MSE is the psychiatric equivalent of the physical examination—a structured, systematic assessment of current mental functioning that documents observations at a specific point in time. Standard MSE components include: Appearance (grooming, hygiene, dress, posture, apparent vs. stated age); Behaviour/psychomotor activity (eye contact, gait, agitation, retardation, tics, level of cooperation); Speech (rate, volume, quantity, articulation—e.g., pressured speech in mania, poverty of speech in depression); Mood and Affect (mood is client's reported sustained emotion [subjective]; affect is nurse's observed emotional expression [objective]; affect described as broad, restricted, blunted, flat, or labile, and as congruent or incongruent with mood); Thought Process (form of thinking: logical, circumstantial, tangential, flight of ideas, loose associations, word salad); Thought Content (what client thinks: delusions, obsessions, phobias, suicidal/homicidal ideation—always assessed directly); Perception (hallucinations [auditory, visual, tactile, olfactory, gustatory] and illusions); Cognition/Sensorium (level of consciousness, orientation to person/place/time, attention, memory [immediate, recent, remote], abstract thinking; Mini-Mental State Examination may be used); Insight (awareness of own illness); Judgment (ability to make sound decisions).

RA 11036 is the first national mental health legislation in the Philippines, signed into law in 2018. Key provisions include: (1) Rights-Based Approach—affirms service users' rights to best available mental health care, confidentiality, informed consent, treatment in least restrictive environment, freedom from discrimination/torture/inhumane treatment; (2) Integration into Primary Care—mandates integration of mental health services into the general health system, including community and barangay levels, and basic health services of local government units; (3) Creation of Philippine Council for Mental Health—an inter-agency body under the Department of Health overseeing implementation and coordination; (4) Mental Health in Schools and Workplaces—requires mental health programs and promotion in educational institutions and workplaces; (5) Suicide Prevention—includes public education to reduce stigma; (6) Informed Consent and Rights of Service Users—includes right to refuse treatment (except specified circumstances) and provisions for supported decision-making and advance directives. Complementary DOH programs include the National Mental Health Program, the National Center for Mental Health (NCMH) in Mandaluyong (which operates the NCMH Crisis Hotline for suicide and mental health emergencies), and integration into the Universal Health Care Act (RA 11223) benefit package.

Psychiatric nursing care is built on the therapeutic use of self—the nurse's genuine presence, authenticity, and emotional availability as a therapeutic tool. Core nursing priorities across all psychiatric settings include: (1) Safety First—assess for risk of harm to self or others at every contact; a client expressing suicidal ideation with a plan is a priority over all other concerns; (2) Establish Trust—through consistency, honesty, acceptance, and non-judgmental presence; (3) Set Clear, Consistent Limits—on unacceptable behaviour while accepting the person; (4) Maintain Therapeutic Milieu—create a safe, structured environment conducive to healing; (5) Self-Awareness—the nurse continuously examines her own feelings, values, and biases so they do not intrude on care (known as reflexivity); (6) Cultural Competence—particularly in the Philippine context, understanding extended family roles, spirituality, and community influences.

Psychiatric nursing includes education to counter mental health stigma and improve outcomes. Key educational messages include: (1) Mental illness is a health condition, not a personal weakness, moral failing, or spiritual curse—this directly counters Filipino cultural stigma; (2) Family involvement is critical given the central role of extended family in Filipino care; families should be educated on recognising warning signs and supporting medication adherence; (3) Crisis resources should be provided, including the NCMH Crisis Hotline (1888-USAP) and local mental health facility contacts; (4) Medication adherence is essential for symptom management and relapse prevention; (5) Follow-up care under RA 11036's community-based model ensures continuity of care at barangay health centres and local facilities.

Mental health status exists on a continuum and is dynamically influenced by biological factors (neurochemistry, genetics, physical health), psychological factors (coping skills, self-concept, past experiences), and sociocultural factors (family, poverty, education, culture, spirituality, social support). A person's position on the mental health–illness continuum shifts as these factors change. For example, a Filipino client with genetic predisposition to depression (biological) experiencing job loss (psychological stressor) without family support (sociocultural deficit) may move toward the illness end of the continuum, while access to family support, medication, and employment assistance could facilitate movement back toward health.

Freud's psychoanalytic theory provides the theoretical foundation for understanding defence mechanisms. The ego (operating on the reality principle) employs unconscious defence mechanisms to protect itself from anxiety arising from conflict between id impulses (demanding gratification) and superego constraints (moral prohibitions). For example, a client who is angry at a parent (id impulse) but cannot consciously accept this anger (superego prohibition) may employ repression (blocking the anger from awareness) or projection (accusing the parent of anger toward them). Understanding this relationship helps nurses recognise that defence mechanisms serve a protective purpose and should not be abruptly confronted.

Erikson's theory provides a framework for understanding what developmental tasks a client should be navigating based on their age. When a client presents with psychiatric symptoms, the nurse asks: 'Which developmental stage is this person in, and which core conflict are they struggling to resolve?' For example, an adolescent client (Identity vs. Role Confusion stage) presenting with depression and self-harm may be struggling with identity formation; a young adult (Intimacy vs. Isolation stage) with anxiety may be avoiding intimate relationships; an older adult (Ego Integrity vs. Despair) with apathy may be struggling to accept their life accomplishments. Interventions are then tailored to support healthy resolution of the developmentally appropriate conflict.

The MSE provides the objective data foundation for formulating psychiatric nursing diagnoses. Specific MSE findings lead to specific nursing diagnoses using NANDA taxonomy: for example, disorganised speech and loose associations (thought process findings) support 'Disturbed Thought Processes'; flat or blunted affect with poverty of speech supports 'Social Isolation' or 'Impaired Verbal Communication'; suicidal ideation with plan and intent supports 'Risk for Self-Directed Violence'; grandiose delusions support 'Disturbed Thought Processes' or 'Risk for Other-Directed Violence'. The MSE thus bridges assessment and diagnosis, guiding priority-setting and intervention selection.

RA 11036's rights-based approach directly shapes how nurses should practice psychiatric nursing. The law affirms service users' rights to informed consent, confidentiality, treatment in the least restrictive environment, and freedom from discrimination. This means that nurses must: obtain informed consent before treatment (not assume it), respect confidentiality while still maintaining safety, advocate for community-based care over hospitalisation when clinically appropriate, and actively work to reduce stigma through education and non-discriminatory practice. For example, rather than paternalistic 'taking over' decision-making, nurses should use supported decision-making approaches, help clients access information, and respect their choices when safe.

In the Philippine cultural context, mental illness is often attributed to spiritual causes (*baliw*, possessed spirits, or divine punishment) rather than biological or psychological causes. This cultural belief, while reflecting strong spirituality (a protective factor), creates significant stigma and barriers to help-seeking. Effective Filipino psychiatric nurses must acknowledge and respect spiritual beliefs while gently introducing the concept of mental illness as a health condition with biological, psychological, and social components. For example, a nurse might say, 'Your family is right that spirituality is important to healing—we can honour that while also addressing the chemical imbalance in your brain that is causing these symptoms. Both can be true.' This culturally sensitive approach reduces shame and increases treatment engagement.

Safety (physiological and security needs) sits at the base of Maslow's hierarchy of needs. In psychiatric nursing, safety assessment—specifically risk of harm to self or others—ALWAYS takes priority over all other needs and interventions. A client expressing suicidal ideation with a plan and intent is a higher priority than a client with self-esteem deficits, despite both needing care. This aligns with Maslow's principle that lower-level needs must be met before higher-level ones; a person at risk of death cannot work on love, belonging, esteem, or self-actualisation. The nurse first assesses safety, implements interventions to reduce risk, and only then progresses to other nursing diagnoses.

The therapeutic use of self—the nurse's genuine presence, consistency, honesty, and non-judgmental acceptance—is the primary mechanism through which psychiatric nursing creates change. Trust is built through reliable, authentic presence over time. Once trust is established, the nurse can gently explore defence mechanisms, challenge maladaptive beliefs, and encourage healthier coping. For example, a client using denial about their illness will not engage in treatment until they trust the nurse. Only through the nurse's consistent, non-judgmental presence—accepting the client while not accepting the denial—can the client gradually move toward insight. This trust also facilitates the client's openness during the MSE and disclosure of suicidal ideation.
