How Collaborative Problem Solving and Triple P Divide Up the Same Household
And how Triple P sharpens Collaborative Problem Solving in return.
Collaborative Problem Solving, often shortened to CPS, is Ross Greene's approach to a child's difficult behavior: instead of imposing a consequence, the adult and child sit down together at a calm moment and name what's actually hard about a specific recurring situation, then build a solution both can live with. Triple P, the Positive Parenting Program, is a tiered set of concrete strategies — specific descriptive praise, planned ignoring of attention-seeking behavior, and predictable routines — that a parent applies consistently across the day, not just during a hard moment. On this reading, CPS supplies the diagnosis for a specific flashpoint and Triple P supplies the steady baseline that makes a calm conversation possible at all; they aren't solving the same problem in the same moment so much as covering different parts of a household's week. Whether running them together changes outcomes beyond either alone has not been studied.
What each one is actually for
Collaborative Problem Solving
CPS, short for Collaborative Problem Solving, is Ross Greene's way of handling a child's outburst — the school refusal, the meltdown over turning off a screen, the same fight three nights running. Instead of reaching for a consequence, you wait for a calm moment, never mid-meltdown, and you and your kid sit down together and ask what's actually hard about this specific situation, not why they keep doing this. Greene calls this conversation Plan B. You're listening for what he calls the unsolved problem: the concrete, nameable thing standing between what you're expecting and what your kid can currently pull off. Once you can both say what that thing is out loud, you build a solution neither of you invented alone and both of you actually agreed to.
Triple P
Triple P, the Positive Parenting Program, hands a parent a small set of concrete moves and asks them to run those moves the same way every day, not just when they remember. Specific praise names the exact thing you liked, out loud, right after it happens — "I like how you put your shoes on the first time I asked" instead of a flat "good job." Planned ignoring means deliberately not reacting to a behavior that only happens to pull your attention, so pulling attention stops working as a strategy for getting it. And a predictable shape to ordinary stretches of the day — the same after-school order, the same bedtime sequence — means fewer decisions get made from scratch, under pressure, in the moment. None of it happens during a flashpoint that's already underway. It happens on every other day, so there are fewer flashpoints to begin with.
What you get out of pairing them
Run only CPS and you get real, honest answers about one specific fight — but a house where every hour is unpredictable keeps generating a new specific fight faster than any number of calm conversations can keep up with. Run only Triple P and the routines hold most days, but nothing in the toolkit tells you what to do on the day a well-run routine still doesn't prevent a meltdown, because the routine was never actually the problem that day. Held together, one supplies the calm baseline the other needs in order to happen at all, and the other supplies a specific diagnosis the first has no built-in way to generate on its own.
What Collaborative Problem Solving rests on
-
Externalizing makes pattern visible
randomised trials
Putting an internal pattern into an external, structured form makes it visible and available for examination instead of remaining implicit and merely enacted.
-
Parts have positive intent
clinical practice
A behavior that looks like misbehavior is usually a mistaken strategy aimed at meeting a legitimate underlying need rather than an expression of badness itself.
-
Collaborative solution generation increases buy in
observational studies
Jointly generating a solution with the person who has the problem produces more durable follow-through than an imposed solution.
What Triple P rests on
-
Consistency strengthens behavior change
clinical practice
Applying a behavior-change strategy consistently, without exceptions, determines whether it produces lasting change.
-
Extinction reduces attention seeking behavior
randomised trials
Withdrawing attention from a behavior that is maintained by attention reduces its frequency over time.
-
Positive reinforcement strengthens behavior
randomised trials
Reinforcing a desired behavior with specific descriptive praise increases how often that behavior occurs.
-
Predictable routines reduce conflict
clinical practice
Predictable structured routines reduce child behavioral problems by lowering uncertainty and testing.
Where they actually meet
CPS and Triple P look opposed on the surface — CPS resists pre-set consequences, Triple P is built around consistent strategies including planned ignoring and reinforcement schedules. But both rest on the same bet at different scope: CPS's principle of positive intent assumes a behavior is a strategy for an unmet need — what Greene calls the unsolved problem, the specific recurring situation a behavior shows up around, named plainly instead of left as "he has tantrums" — not defiance chosen freely. Triple P's consistency and routine principles assume something close to the same thing at a structural level: children do better when the environment around them is legible and predictable, so they aren't left guessing what happens next. CPS operates on a specific flashpoint through direct conversation; Triple P operates on the whole environment through steady default patterns. CPS is what happens in the room during a hard moment; Triple P is what's already true before that moment starts.
The principle underneath both
A recurring behavior isn't decided fresh each time it happens; it's shaped by what came immediately before it and by what the environment has already trained a child to expect. CPS reads that shaping backward, working from one specific outburst to the mismatch that produced it. Triple P builds it forward, setting the environment up so fewer mismatches occur in the first place. Read backward or built forward, the same claim is doing the work in both: change what comes before a behavior, in either direction, and the behavior changes without ever needing to be argued with directly in the moment it happens.
What that makes the real goal
If that's the mechanism, the goal both are chasing is narrowing the daily gap between what a household expects of a child in a given moment and what that child can actually deliver in that moment — closing it by adjusting the expectation where it's genuinely too high for right now, and closing it by making the moment itself more predictable where the demand is fine but the surrounding chaos isn't. Either practice, run on its own, closes only half of that gap.
Other practices that serve the same goal
Functional Behavior Assessment, standard practice in special education, chases the identical target through a more formal process: a trained observer tracks what happens right before a behavior and what happens right after it, across several instances, to work out what the behavior is actually accomplishing for the child — attention, escape from a hard task, sensory relief — before anyone tries to change it. The antecedent-behavior-consequence read it relies on carries decades of applied-behavior-analysis research behind it. Motivational Interviewing, developed for substance-use counseling and now used far more broadly, closes the same gap from the adult's side of the conversation: instead of the adult supplying the diagnosis, a set of specific, non-leading questions draws a person's own reasons for change out of them, on the reasoning that a reason someone states themselves holds up under pressure better than one handed to them — close to the same buy-in logic CPS's own literature cites for why a jointly generated solution outlasts an imposed one.
A tradition that already does this
Positive Behavior Support, developed inside special education through the 1980s and 90s, already runs both halves of this as one continuous process rather than two practices borrowed from different fields: a functional assessment to find out what a behavior is accomplishing, followed directly by redesigning the routine and the physical environment around what that assessment found. It arrived at the diagnose-then-restructure shape independently, in a classroom rather than a living room, before either Collaborative Problem Solving or Triple P existed under names a parent would recognize today.
Using Collaborative Problem Solving to enhance Triple P
Triple P's tiered strategies work best matched to what's actually driving a behavior, and Triple P on its own has no built-in step for finding that out — a planned-ignoring strategy aimed at attention-seeking won't touch a meltdown that's actually about an unmet need for structure. CPS's practice of sitting with the child and jointly naming the unsolved problem behind a specific recurring flashpoint gives a parent using Triple P's toolkit the information to pick the right tier instead of guessing. Concretely: before reaching for planned ignoring or a reward chart, run one short Plan B conversation on the specific flashpoint first — five minutes, at a calm moment, asking what's actually hard about it — and let what comes back decide which Triple P tool actually fits, rather than applying the tool that happened to work last time on something else.
Using Triple P to enhance Collaborative Problem Solving
CPS's collaborative conversations take real time and real regulation from both people, and they don't happen well in a household where the ordinary hours are chaotic — nobody sits down calmly to diagnose an unsolved problem while the whole evening is already off the rails. Triple P's routines and specific, descriptive praise build the baseline stability that makes a CPS conversation possible to have calmly in the first place, instead of every conversation happening only in crisis. Concretely: pick one predictable stretch of the day — right after school, or right before bed — and hold it the same way every day for two weeks before attempting a Plan B conversation about anything that happens inside it. A predictable stretch gives a hard conversation somewhere stable to land.
Your kid is mid-meltdown over homework, again
You've had this fight four times this week and you're out of patience. Rather than reaching for a consequence, you wait for a calmer moment later and ask what's actually hard about homework time — not "why do you keep doing this" but "what's up with homework." The unsolved problem that comes out might be concrete: the room is too loud, or the first problem on the page tends to look impossible. That's the CPS move. Separately, and not in that moment, you and your co-parent had already agreed on a predictable after-school routine — snack, twenty minutes free time, then homework at the same table every day — because Triple P's routines principle says predictability itself lowers how often these flashpoints start. Neither piece is doing the other's job, and by the third week the routine has quietly absorbed two of the four fights before they start, leaving the Plan B conversation to handle the one that routine alone couldn't touch.
When this is worth reaching for
The routine has been running for weeks now — same snack, same after-school order, same bedtime sequence — and one specific flashpoint keeps breaking through it anyway, always over the same thing. That's the moment for a Plan B conversation aimed at that one flashpoint specifically, not a review of the whole routine, since the routine is clearly already doing its job everywhere else. It also matters early, before a household has much of a routine in place at all: a first CPS conversation can surface which stretches of the day are genuinely the unpredictable ones, which is exactly the information Triple P's routine-building needs in order to target the right hours instead of guessing at all of them.
Where this does not apply
CPS treats a behavior as a skill gap to be jointly solved, and some Triple P tiers — planned ignoring in particular, deliberately withdrawing attention from a behavior maintained by attention — assume the opposite: that the behavior doesn't need a conversation, it needs to stop being reinforced. Applying both to the same flashpoint in the same week can send a child contradictory messages — one where an outburst gets a long collaborative conversation and one where it gets studied silence. They tend to work better aimed at different flashpoints than layered onto the identical one, and a parent picking both at once for one behavior should pick one and give it two full weeks before switching.
What the evidence does and does not support
Externalizing a pattern into a form both people can examine carries the strongest backing here — randomized-trial support across several unrelated applications, which is where both CPS's founding principle and Triple P's insistence on routine draw much of their credibility. Specific praise and planned ignoring, the two Triple P tools named above, each have their own randomized trials behind them individually. CPS's read that a difficult behavior expresses an unmet need rather than badness comes from clinical practice and outcome tracking, a lower evidentiary bar than a randomized trial clears. Nobody has run one household through both programs at once and compared it against a household that got only one — the account above is an argument from how the two mechanisms interact day to day, not a citation to a study that tested the combination.
