    • Psychoanalytic Theory• Behavior motivated by subconscious thoughts and feelings• Discovering client’s unconscious and repressed thoughts, feelings, and conflicts believed to cause anxiety and on helping the client to gain the insight into and resolve these conflicts and anxieties (Theory of Anxiety)• Topographical model of the mind:a. Conscious - perceptions, thoughts, and emotions that exist in the person’s awarenessb.

    • Psychoanalytic Theory• The Stages of Psychosexual Development1. Oral stage2. Anal stage3. Urethral stage4. Phallic stage5. Latency stage6. Genital stage
    • Oral StageObjectives To establish a trusting dependence on nursing and sustaining objects, to establish comfortable expression and gratification of oral libidinal needs without excessive conflict or ambivalence from oral sadistic wishesPatholological traits Excessive optimism, narcissism, pessimism (often seen in depressive states), and demandingness Oral characters are often excessively dependent and require others to give to them and to look after them Oral characters are often extremely dependent on objects for the maintenance of their self-esteem Envy and jealousy are often associated with oral traitsCharacter traits Successful resolution leads to capacities to give and receive from others without excessive dependence or envy and capacity to rely on others with a sense of trust, as well as with a sense of self- reliance and self-trustNursing Nurses with postgraduate training can conduct psychodynamicresponsibilities therapy Nurse can use this theory in interpreting client’s behavior Nurses’ must give attention to the client’s defense mechanisms
    • Anal StageObjectives Essentially a period of striving for independence and separation from the dependence on and control by the parentPatholological traits Orderliness, obstinacy, stubbornness, willfulness, frugality, and parsimony Heightened ambivalence, lack of tidiness, messiness, defiance, rage, and sadomasochistic tendencies Most typically seen in obsessive-compulsive neurosesCharacter traits Successful resolution provides the basis for the development of personal autonomy, a capacity for independence and personal initiative without guilt, a capacity for self-determining behavior without a sense of shame or self-doubt, a lack of ambivalence and a capacity for willing cooperation without either excessive willfulness or sense of self-diminution or defeatNursing Nurses with postgraduate training can conduct psychodynamicresponsibilities therapy Nurse can use this theory in interpreting client’s behavior Nurses’ must give attention to the client’s defense mechanisms
    • Urethral StageObjectives Issues of control and urethral performance and loss of controlPatholological traits Competitive, ambitious, penis envy, issues in control and sharingCharacter traits Provides a sense of pride and self-competence derived from performance. This is when a small boy can imitate and match his father’s more adult performance. The resolution sets the stage for budding gender identity and subsequent identificationsNursing Nurses with postgraduate training can conduct psychodynamicresponsibilities therapy Nurse can use this theory in interpreting client’s behavior Nurses’ must give attention to the client’s defense mechanisms
    • Phallic StageObjectives Focus erotic interest in the genital area and genital functions, which lays the foundation for gender identity and serves to integrate the residues of previous stages of psychosexual development into a predominantly genital-sexual orientationPatholological traits Oedipal complex Castration complex in males and penis envy in females Conflicts in the previous stages may resume, so that fixations or conflicts that derive from any of the preceding stages can contaminate and modify the oedipal resolutionCharacter traits Provides the foundation for an emerging sense of sexual identity; a sense of curiosity without embarrassment, initiative without guilt, as well as a sense of mastery not only over objects and persons in the environment but also over internal processes and impulsesNursing Nurses with postgraduate training can conduct psychodynamicresponsibilities therapy Nurse can use this theory in interpreting client’s behavior Nurses’ must give attention to the client’s defense mechanisms
    • Latency StageObjectives Further integration of oedipal identifications and a consolidation of sex-role identity and sex roles Mastery of skills Broadening of significant figures outside the family, such as teachers, coaches, and other adultsPatholological traits Lack of development of inner controls or an excess of them. The lack of control can lead to a failure of the child to sufficiently sublimate energies in the interests of learning and development of skills; an excess of inner control can lead to premature closure of personality development and the precocious elaboration of obsessive character traitsCharacter traits The child can develop a sense of industry and a capacity for mastery of objects that allows autonomous function with a sense of initiative without running the risk of failure or defeat or a sense of inferiorityNursing Nurses with postgraduate training can conduct psychodynamicresponsibilities therapy Nurse can use this theory in interpreting client’s behavior Nurses’ must give attention to the client’s defense mechanisms
    • Genital StageObjectives The ultimate separation from dependence on and attachment to the parents and the establishment of mature, nonincestuous, object relationsPatholological traits Fixations Personality disorders Identity diffusion in Erik Erikson’s Psychosocial StagesCharacter traits Sets the stage normally for a fully mature personality with a capacity for a full and satisfying capacity for self-realization and meaningful participation in the areas of work and love and in the creative and productive application to satisfying and meaningful goals and valuesNursing Nurses with postgraduate training can conduct psychodynamicresponsibilities therapy Nurse can use this theory in interpreting client’s behavior Nurses’ must give attention to the client’s defense mechanisms
    • Psychosocial Stages of Development• Erik Homburger Erikson• The eight stages represent points along a continuum of development in which physical, cognitive, instinctual, and sexual changes combine to trigger an internal crisis whose resolution results in either psychosocial regression or growth and the development of specific virtues
    • Psychosocial Stage Associated Virtue Related Forms of PsychopathologyTrust vs. mistrust Hope Psychosis Addictions DepressionAutonomy vs. shame and Will Paranoiadoubt Obsessions Compulsions ImpulsivityInitiative vs. guilt Purpose Conversion disorder Phobia Psychosomatic disorder InhibitionIndustry vs. inferiority Competence Creative inhibition InertiaIdentity vs. role confusion Fidelity Delinquent behavior Gender-related identity disorders Borderline psychotic episodes
    • Psychosocial Stage Associated Virtue Related Forms of PsychopathologyIntimacy vs. isolation Love Schizoid personality disorderGenerativity vs. stagnation Care Mid-life crisis Premature invalidismIntegrity vs. despair Wisdom Extreme alienation Despair Nursing responsibilitiesNurses commonly perform Erikson’s developmental stages
    • Jean Piaget’s Cognitive Development• Four stages• Each stage is a prerequisite for the following one, but the rate at which different children move through different stages varies with their native endowment and environmental circumstances
    • Age Period Cognitive Developmental Characteristics0 – 1.5 (to 2) Sensorimotor child develops a sense of self separate from the environment and the concept of object permanence (an object does not cease to exist just because they are out of sight (formation of mental images))2–7 Preoperations ability to express self with language, subperiod understands the meaning of symbolic gestures, and begins to classify objects7 - 11 Concrete operations application of logic to thinking, but thinking is still concrete11 – end of Formal operations more abstract thinkingadolescenceNursing Useful when nurses work with childrenresponsibilities Nurse may better understand what the child means if the nurse is aware of his or her own level of cognitive development Teaching children is often structured with their cognitive development in mind
    • Harry Stack Sullivan• Interpersonal Relationship and Milieu therapy• Nurse focuses on the nurse-patient relationship, the vehicles through which the patient becomes healthy• Nurse counsel patients by developing therapeutic relationship• Anxiety interventions is an important nursing role• Nurses use the nurse-patient relationship as a corrective interpersonal experience for patient
    • Harry Stack Sullivan• Interpersonal theory• Milieu therapy• Three modes of experiencing and thinking:1. Protaxic mode – undifferentiated thought that cannot separate the whole into parts or use symbols; occurs normally in infants and also appears in patients with schizophrenia2. Parataxic mode – events are casually related of temporal or serial connections; no perception of logical relatonships3. Syntaxic mode – logical, rational, and most
    • Harry Stack Sullivan• The three personifications of me:1. Good me – everything that you like about yourself that you let others see2. Bad me – things that you don’t like about yourself that you would prefer others not to see, but you accept them as a part of you3. Not me – all the negative aspects of yourself, from feelings, thoughts, experiences that you do not accept as a part of you, and as a result these are buried deep within the

    • Nursing Implications• Hildegard Peplau• Harry Stack Sullivan1. Nurse focuses on the nurse-patient relationship, the vehicles through which the patient becomes healthy2. Nurse counsel patients by developing therapeutic relationship3. Anxiety interventions is an important nursing role
    • Carl Rogers• Client-centered theory• Or person-centered theory• The major concepts are self-actualization and self-direction• Persons are born with the capacity to direct themselves in the healthiest way toward a level of completeness called self-actualization• Focus is on the client rather than the therapist• Each client experiences the world differently and he or she knows this the best
    • Carl Rogers• Nurse-patient interaction is based on humanistic principles:a. Positive regardb.Empathyc. Geunineness
    • Abraham Maslow• A leader in humanistic psychology• Hierarchy of needs• As the more primitive needs, such as hunger and thirst are satisfied, more advanced psychological needs, such as affection and self-esteem, become the primary motivators• Self-actualization is the highest need
    • Abraham Maslow• Anxiety disorders as well as behavioral problems may arise if needs are not met• Nurse-patient interaction is based on humanistic principles:a. Positive regardb.Empathyc. Geunineness
    • Theory Focus Mental Health Nursing Alterations ResponsibilitiesCognitive therapy How the person Anxiety disorders Client is encouraged perceives or to initiate topics of interprets his or her concern experience and Nurse listens determines how he carefully to the client or she feel and The nurse uses the behaves reflective listeningRational emotive Identifies irrational approaches to helptherapy beliefs that people the patient gain self- use to make understanding themselves unhappy The nurse helps the patient examineViktor Frankl and Search for meaning alternative choicesLogotherapy (logos) is the central theme Spirituality and grief counseling(Videbeck, pages 17 to 24 and 44 to 56 Student Guide, pages 83 to 90)

    • Biomedical Theory• Mental illness can be a result of something physical• Mental illness may be a symptom of an organic disease• Mental illness has an organic basis
    • Review of nervous system - neuroanatomy
    • Major NeurotransmittersType Mechanism of Action Physiologic EffectsDopamine Excitatory Controls complex movements, motivation, cognition, regulates emotional responseNorepeniphrine or Excitatory Causes changes inattention,noradernaline learning and memory, sleep and wakefulness, moodEpinephrine or adrenaline Excitatory Controls fight or flight responseSerotonin Inhibitory Controls food intake, sleep and wakefulness, temperature regulation, pain control, sexual behaviors, regulation of emotions Videbeck, page 21
    • Major NeurotransmittersType Mechanism of Action Physiologic EffectsHistamine Neuromodulator Controls alertness, gastric secretions, cardiac stimulation, peripheral allergic responsesAcetylcholine Excitatory or inhibitory Controls sleep and wakefulness cycle, signals muscles to become alertNeuropeptides Neuromodulators Enhance, prolong, inhibit, or limit the effects of principal neurotransmittersGlutamate Excitatory Results in neurotoxicity if levels are too highGamma-aminonutytic acid Inhibitory Modulates other(GABA) neurotransmitters Videbeck, page 21
    • Proposed Clinical Relevance of Neurotransmitters• Serotonin – antidepressant action; anxiolytic; possible role in locomotor activity, aggression; regulation of appetite, anxiety, seizures; target of hallucinogens, antipsychotics; cognitive enhancement• Histamine – produce sedation as well as arousal; weight gain as well as appetite suppression• Dopamine – D1 and D2 receptor stimulation synergistic; required for stimulant effects of
    • Brain Imaging Techniques• Computed tomography (CT) – also called computed axial tomography (CAT), is a procedure in which a precise x-ray beam takes cross sectional images (slices) layer by layer• Magnetic resonance imaging MRI) – a type of body scan, an energy field is created with a huge magnet and radio waves and the energy field is converted to visual images or scan
    • Brain Imaging Techniques• Positron emission tomography (PET) and single positron emission computed tomography) – are used to examine the function of the brain, where radioactive substances are injected into the blood; the flow of those substances in the brain is monitored as the client performs cognitive activities instructed by the operator• Limitations of brain imaging techniques 1. The use of radioactive substances in PET and SPECT is frightening to some people 2. Expensive 3. Some clients cannot tolerate the procedure 4. Many changes in some disorders like
    • Spirituality• Affirmation of life in relationship with God, self, community, and environment that nurtures and celebrated wholeness (http://www.rcpsych.ac.uk/pdf/nl6_eagger.pdf)
    • Spiritual Theory• Focus: Relationship of Man and God – Man’s relationship with God is destroyed because of sin. – Restlessness (anxiety)is because man is separated from God. – Sin produces fear – Sin separates man from God. – The only way to have peace is to reestablish relationship with God through Jesus Christ – (Christianity)
    • Spiritual TheorySpirituality• things beyond biological experience• Gives depth and meaning to life• Presence of higher power• Higher purpose• Higher principles• “Spirituotherapy”
    • Spirituotherapy• To establish relationship with God there are three things that a man should do: – Acknowledge being sinful – Repentance – Receive God’s offer of salvation through His son, Jesus Christ. “God did not give us the spirit of fear but power, love and SOUND MIND.”
    • Nursing application• The nurse should first assess her own relationship with God.• Praying and reading the gospel with the patient is one of the functions of the nurse.• The nurse must respect his/her patient’s belief but need not sacrifice his/her salvation.
    • Basic Concepts• Apart from God , man is not whole.• God is able to forgive past experiences( Intrapsychic) and erase painful experiences in the past. The only way man can learn to do good is through God’s grace (unmerited favor) Man cannot be good on His own.“ Its not by might nor by power but by my spirit ,says the Lord.” (the Bible)
    • Actual People in History with Alterations with Mental Health• Ted Bundy – born out of wedlock, mother remarried and raised him as her younger brother, had a difficult relationship with his stepfather, became a serial killer who could have been responsible for killing 100 girls and women.
