Final answer:
In summary, Whitaker's concept involves the therapist winning the power struggle while the family overcomes the emotional struggle. Empowerment theory ties into these therapy dynamics. Additionally, in Erik Erikson's developmental theory, the challenge faced by older people is overcoming despair to achieve integrity.
Step-by-step explanation:
Referring to the principles of therapeutic intervention and the role dynamics within a therapy session, the statement Whitaker supported the idea that the power struggle must be won by the therapist, while the emotional struggle must be won by the family aligns strongly with the relational dynamics approached in psychotherapy and family systems therapy. Whitaker was a therapist known for his work with families, where notions of power and emotional conflict are often central themes. Empowerment theory similarly describes the nuanced interactions within a therapeutic environment. In this context, the therapist aims to claim authority in the therapeutic relationship, without overwhelming the family's autonomy, guiding them towards overcoming their own struggles within the family dynamic.
Erikson's developmental stages refer to distinct challenges faced at different life stages. The correct answer to the question regarding which challenge older people must struggle with according to Erikson's theory is, 'Overcoming despair to achieve integrity'. This is a reference to Erikson's eighth and final stage of psychosocial development, where the main conflict centers around 'Integrity vs. Despair'.
