Needs assessment

A structured process of gathering data to identify gaps between current and desired conditions in a population, so that programs can target the most important problems with scarce resources.

Related: Priority population, Logic model
Risk and protective factors

Conditions or attributes that respectively raise or lower the likelihood of a problem outcome. Prevention planning weighs both, aiming to reduce risk and strengthen protection at individual, family, school, and community levels.

Related: Needs assessment, Theory of change
Evidence-based practice

An intervention or approach whose effectiveness is supported by credible research, ideally several rigorous studies or systematic reviews, and which is selected and delivered consistent with the conditions under which it was tested.

Related: Systematic review, Implementation fidelity, Cultural adaptation
Systematic review

A structured, protocol-driven synthesis of all relevant studies on a question, using explicit search and appraisal rules. Meta-analysis is a related technique that statistically pools effect sizes across studies.

Related: Evidence-based practice, Secondary data
Informed consent

The voluntary agreement of a person to take part in research or programming after being told the purpose, procedures, risks, benefits, and alternatives, documented in language the person can understand.

Related: Institutional Review Board, Qualitative data
Institutional Review Board

An independent committee that reviews research involving human subjects before it begins, checking that risks are minimized, selection is fair, and consent and privacy protections meet ethical and regulatory standards.

Related: Informed consent, Secondary data
Probability sampling

A selection method in which every member of a defined population has a known, non-zero chance of being chosen, supporting representativeness and allowing estimates of sampling error.

Related: External validity, Comparison group
Reliability

The consistency of a measurement or instrument: whether repeated administration, alternate forms, or different raters produce similar results under comparable conditions.

Related: Validity, Performance indicator
Validity

The degree to which an instrument or study measures or demonstrates what it claims to, encompassing content, construct, and criterion evidence and, for studies, internal and external forms.

Related: Reliability, External validity
Qualitative data

Non-numeric information such as interview transcripts, focus group notes, or observation records, analyzed for themes and meaning. It is useful for explaining how and why a program works in context.

Related: Data triangulation, Informed consent
Secondary data

Information already collected by someone else for another purpose, such as census files, school records, or surveillance surveys, reanalyzed to answer a new question at lower cost but with less control over quality.

Related: Needs assessment, Systematic review
Logic model

A one-page picture linking resources, activities, outputs, and short- and long-term outcomes, showing the assumed pathway by which a program is expected to produce change; it guides planning, monitoring, and evaluation.

Related: Theory of change, SMART objectives, Process evaluation
Theory of change

A narrative and diagrammed explanation of how and why an intervention is expected to work, spelling out the preconditions, mechanisms, and assumptions that must hold for intended outcomes to occur.

Related: Logic model, Risk and protective factors
SMART objectives

Program objectives written to be specific, measurable, achievable, relevant, and time-bound, so that progress can be observed and judged rather than merely described in general terms.

Related: Performance indicator, Logic model
Priority population

The subgroup a program deliberately targets because its need, risk, or burden is greatest and resources are too limited to serve everyone; defining it sharply shapes recruitment, design, and messaging.

Related: Needs assessment, Reach
Stakeholder engagement

The deliberate involvement of people with an interest in the program, including participants, staff, funders, partners, and policymakers, in planning and decisions, which builds trust, improves fit, and supports later use of findings.

Related: Community readiness, Dissemination
Community readiness

The degree to which a community's leaders, resources, and attitudes are prepared to address an issue. Assessing it helps planners match strategies to the current stage rather than pushing ahead prematurely.

Related: Stakeholder engagement, Capacity building
Capacity building

Activities that strengthen the skills, infrastructure, partnerships, and systems a community or organization needs to plan, deliver, and sustain programs on its own over time.

Related: Sustainability plan, Technical assistance
Sustainability plan

A written strategy for keeping a program's benefits going after initial funding ends, covering diversified funding, institutional hosting, trained local staff, policy support, and ongoing data use.

Related: Capacity building, Dissemination
Cultural adaptation

The systematic modification of a program's content, language, or delivery so it fits the culture, values, and context of a new population while preserving the core elements linked to its effectiveness.

Related: Implementation fidelity, Priority population
Implementation fidelity

The extent to which a program is delivered as designed, covering adherence to core components, dosage, quality of delivery, participant responsiveness, and differentiation from other services.

Related: Cultural adaptation, Dosage, Process evaluation
Dosage

The amount of program content actually received by participants, expressed as sessions attended, hours of exposure, or activities completed; too little exposure can make an otherwise sound program look ineffective.

Related: Implementation fidelity, Reach
Pilot test

A small-scale trial run of a program or instrument in a real setting before full launch, used to surface practical problems, estimate recruitment and time demands, and refine procedures cheaply.

Related: Formative evaluation, Implementation barrier
Technical assistance

Ongoing, tailored support such as coaching, consultation, troubleshooting, and materials, given to implementers so they can deliver a program competently and solve problems as they arise.

Related: Capacity building, Continuous quality improvement
Reach

The proportion and representativeness of the intended population that actually participates in or receives a program; weak reach limits potential impact even when the intervention itself works well.

Related: Dosage, Priority population
Monitoring

Continuous, routine collection of data on activities, outputs, and participation during delivery, giving managers timely signals about whether the plan is being carried out and where adjustments are needed.

Related: Performance indicator, Continuous quality improvement
Implementation barrier

A condition that obstructs delivery as intended, such as insufficient time, unclear roles, competing demands, or staff turnover; identifying barriers early supports targeted, practical solutions.

Related: Technical assistance, Pilot test
Continuous quality improvement

A cyclic, data-driven approach, often plan-do-study-act, in which teams make small changes, measure results, and refine repeatedly to improve processes and outcomes over time.

Related: Monitoring, Formative evaluation
Formative evaluation

Evaluation conducted during development or early delivery to improve a program, examining feasibility, acceptability, and emerging implementation issues rather than judging final results.

Related: Process evaluation, Pilot test
Summative evaluation

Evaluation carried out to judge a program's overall merit or worth at a defined point, typically asking whether intended outcomes were achieved and whether benefits justify the costs.

Related: Outcome evaluation, Cost-benefit analysis
Process evaluation

Examination of how a program was delivered, including activities, reach, fidelity, dose, and participant response, used to document implementation and explain why outcomes did or did not appear.

Related: Implementation fidelity, Formative evaluation
Outcome evaluation

Measurement of changes in the target population's knowledge, attitudes, behaviors, or conditions that the program intended to affect, ideally compared with what would have happened without it.

Related: Summative evaluation, Comparison group
Performance indicator

A specific, measurable variable tracked to show whether an activity or objective is on course, such as the percentage of participants completing a program or the rate of a target behavior.

Related: Monitoring, SMART objectives
Comparison group

Participants in an evaluation who do not receive the program, or who receive an alternative, providing a benchmark against which the intervention group's changes can be judged.

Related: Random assignment, Outcome evaluation
Random assignment

Allocating participants to intervention or comparison conditions by chance, which, with adequate numbers, makes groups similar on average at baseline and reduces selection bias.

Related: Comparison group, External validity
Data triangulation

Combining multiple data sources, methods, or observers to examine the same question, so that conclusions rest on converging evidence rather than a single potentially flawed measure.

Related: Qualitative data, Reliability
External validity

The extent to which findings from a study can be generalized to other populations, settings, and times, which depends heavily on how representative the sample and study conditions were.

Related: Random assignment, Probability sampling
Dissemination

The planned sharing of evaluation findings and program materials with audiences who can use them, including staff, partners, funders, policymakers, and the public, in formats suited to each.

Related: Stakeholder engagement, Summative evaluation
Cost-benefit analysis

A comparison of a program's monetary costs with the estimated monetary value of its benefits, used to judge whether returns justify the investment; it requires assumptions that should be stated openly.
