Three family theories for public health nursing
Three theories, each with strengths and weaknesses, and then a defended choice. The choice is the graded part, and it has to turn on what public health nursing actually does — work with populations of families, not one family at a time.

Three theories, strengths and weaknesses, then a choice
The structure is explicit and worth following literally: explain three named theories, give the strengths and the weaknesses of each, then say which is most beneficial to you as a public health nurse and why. Most posts do the explaining well and then treat the final choice as a preference. It is the graded part. Family Systems Theory treats the family as an interdependent whole with boundaries and feedback, so a change in one member reverberates — powerful for understanding why an intervention aimed at one person fails, weaker on developmental change over time and criticised for how it handles power and abuse within a family. Family Developmental and Life Cycle Theory organises families into predictable stages with tasks attached, which is useful for anticipating needs, but its traditional stage sequence fits an increasingly small share of real families, which is a weakness worth stating plainly rather than softening.
Bioecological Systems Theory is the one that usually wins the argument for public health nursing, and it is worth saying why rather than asserting it. Its nested systems — from the immediate microsystem out through the exosystem and macrosystem to the chronosystem — map directly onto the determinants a public health nurse actually works with: housing, the parent's employer, transport, policy, and change over time. It is the only one of the three that reaches outside the family to the conditions surrounding it, which is precisely the level at which population interventions operate. Its weakness is real too and should be named: its breadth makes it hard to operationalise and it offers less guidance on the interior dynamics of a single household. The strongest posts note that these theories are not rivals — one for the population level, another for the family in front of you. Saying so is more sophisticated than declaring a winner.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Explain three family theories in terms of what each takes as its unit of analysis.
- 02State a genuine weakness of each theory rather than only its strengths.
- 03Defend a theory choice by reference to the level at which public health nursing operates.

Course-wide instructions that accompany this question
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Discussion: Achieving healthy outcomes for families Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument. ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours. Discussion: Achieving healthy outcomes for families

Family Systems Theory
Explain interdependence, boundaries and feedback, then give its strength and its limits.
Family Developmental and Life Cycle Theory
Explain stages and developmental tasks, and note how poorly the traditional sequence fits many families.
Bioecological Systems Theory
Explain the nested systems and the chronosystem, and note the difficulty of operationalising it.
Choose, and justify by level
Argue which theory best fits work with populations of families and say why the others do not.
Note the complementarity
Observe that the theories operate at different levels and can be used together.
Primary sources for family and bioecological theory
Recommended databases
- CINAHL
- PsycINFO
- PubMed Central
- Your course text on family nursing
- CDC social determinants resources
Search sequence
- 1.Find a primary or authoritative account of each theory rather than relying on one textbook chapter for all three.
- 2.Check that you are using the bioecological formulation rather than the earlier ecological one — the difference matters and markers notice.
- 3.Search for a public health nursing application of your chosen theory to support the final section.
- 4.Look for a published critique of each theory so the weaknesses are cited rather than invented.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.

Review before submission
Common mistakes
- Describing the theories well and then choosing one by preference rather than by argument.
- Omitting weaknesses, which the prompt asks for explicitly.
- Attributing bioecological systems theory to its early formulation and missing the bioecological revision.
- Treating the theories as competitors when they operate at different levels.
Submission checklist
- Are all three theories explained, not just named?
- Does each have a stated weakness as well as a strength?
- Is the final choice argued from what public health nursing does?
- Are primary theorists cited rather than only a textbook summary?
