Interpreting Assessment Results

Learn to interpret assessment scores, understand clinical significance, identify reliable change, and communicate findings effectively to clients and referrers.

Understanding Assessment Scores​

Score Components​

Most assessments in Praxi provide the following information:

ComponentDescription
Total scoreSum of all item responses
Severity bandClinical category (e.g., minimal, mild, moderate, severe)
SubscalesDomain-specific scores (where applicable, e.g., DASS-21)
Item responsesIndividual answers for detailed review
PercentileComparison to normative sample
Risk flagsCritical items highlighted for attention

Risk levels recorded in the client's safety assessment are the clinician's judgement. Praxi does not combine those domains into an overall risk rating. Exports retain the recorded domain levels and formulation.

For C-SSRS, review the recorded items. A category may be shown only for an identified instrument version with its published category and citation, using the Assessment summary pattern. The current structured risk record does not provide that mapping, so it shows no software-derived C-SSRS category.


Scoring Tables for Core Assessments​

PHQ-9 (Patient Health Questionnaire-9)​

Items: 9 questions rated 0-3 over the past 2 weeks

Response options:

  • 0 = Not at all
  • 1 = Several days
  • 2 = More than half the days
  • 3 = Nearly every day

Severity cut-offs:

ScoreSeverityRecommended clinical action
0-4MinimalNo treatment indicated; monitor
5-9MildWatchful waiting; repeat PHQ-9 at follow-up
10-14ModerateTreatment plan warranted; counselling and/or medication
15-19Moderately severeActive treatment; consider medication review
20-27SevereImmediate treatment; psychiatry referral strongly recommended

Diagnostic threshold: Score of 10+ suggests probable major depression (sensitivity 88%, specificity 88% for major depressive disorder).

Critical item: Item 9 ("Thoughts that you would be better off dead or of hurting yourself") requires immediate follow-up if score > 0.

Reliable Change Index: 6 points

Item 10 (functional impairment): Not included in total score but provides important context about impact on daily functioning.


GAD-7 (Generalised Anxiety Disorder-7)​

Items: 7 questions rated 0-3 over the past 2 weeks

Response options:

  • 0 = Not at all
  • 1 = Several days
  • 2 = More than half the days
  • 3 = Nearly every day

Severity cut-offs:

ScoreSeverityRecommended clinical action
0-4Minimal anxietyMonitor; psychoeducation
5-9Mild anxietyWatchful waiting; relaxation techniques
10-14Moderate anxietyTreatment indicated; CBT recommended
15-21Severe anxietyActive treatment strongly recommended; consider medication

Diagnostic threshold: Score of 10+ indicates probable generalised anxiety disorder (sensitivity 89%, specificity 82%).

Reliable Change Index: 5 points


DASS-21 (Depression Anxiety Stress Scales)​

Items: 21 questions rated 0-3 over the past week

Response options:

  • 0 = Did not apply to me at all
  • 1 = Applied to me to some degree, or some of the time
  • 2 = Applied to me to a considerable degree, or a good part of time
  • 3 = Applied to me very much, or most of the time
Scoring Note

DASS-21 subscale scores must be multiplied by 2 to align with DASS-42 norms. Praxi does this automatically.

Subscale items:

  • Depression: Items 3, 5, 10, 13, 16, 17, 21
  • Anxiety: Items 2, 4, 7, 9, 15, 19, 20
  • Stress: Items 1, 6, 8, 11, 12, 14, 18

Depression subscale severity (after x2):

ScoreSeverityDescription
0-9NormalWithin normal range
10-13MildSome depression symptoms
14-20ModerateSignificant symptoms; treatment indicated
21-27SevereSevere symptoms; active treatment required
28+Extremely severeCritical level; urgent intervention

Anxiety subscale severity (after x2):

ScoreSeverityDescription
0-7NormalWithin normal range
8-9MildSome anxiety symptoms

15-18MildSome stress symptoms
19-25ModerateSignificant symptoms; intervention indicated
26-33SevereSevere symptoms; active intervention required

Critical items:

  • Item 21 ("I felt that life was meaningless") - follow up at any endorsement
  • Item 10 ("I felt that I had nothing to look forward to") - follow up if score 3

Reliable Change Index: 7 points per subscale


K10 (Kessler Psychological Distress Scale)​

Items: 10 questions rated 1-5 over the past 4 weeks

Response options:

  • 1 = None of the time
  • 2 = A little of the time
  • 3 = Some of the time
  • 4 = Most of the time
  • 5 = All of the time
Australian Standard

The K10 is the recommended outcome measure for Australian Medicare-funded mental health services. It is used in the Australian National Survey of Mental Health and Wellbeing.

Severity cut-offs:

ScoreLevelClinical interpretation
10-19LowLikely to be well
20-24ModerateLikely to have a mild mental disorder
25-29HighLikely to have a moderate mental disorder
30-50Very highLikely to have a severe mental disorder

Note: Some sources use slightly different cut-offs (10-19, 20-24, 25-29, 30-50). Praxi uses the original Andrews & Slade (2001) thresholds.

Critical items:

  • Item 4 ("About how often did you feel hopeless?") - score 4-5 requires follow-up
  • Item 10 ("About how often did you feel worthless?") - score 4-5 requires follow-up

Reliable Change Index: 5.5 points


Critical Items and Risk Flags​

What Are Critical Items?​

Critical items are questions that warrant immediate clinical attention, regardless of total score. They typically relate to:

  • Suicidal ideation
  • Self-harm thoughts
  • Hopelessness
  • Worthlessness
  • Life meaninglessness

Critical Items by Assessment​

AssessmentItemContentTrigger
PHQ-9Item 9"Thoughts that you would be better off dead or of hurting yourself"Any score > 0
DASS-21Item 21"I felt that life was meaningless"Any score > 0
DASS-21Item 10"I felt that I had nothing to look forward to"Score = 3
K10Item 4"About how often did you feel hopeless?"Score 4-5
K10Item 10"About how often did you feel worthless?"Score 4-5
C-SSRSMultipleSuicidal ideation and behaviour itemsAny ideation endorsed

Responding to Critical Item Endorsement​

The results banner says "Positive screen. For your clinical judgement." Use Open safety plan and risk to review the client's record. A positive screen is not a Praxi risk rating or a recommendation to administer another instrument.

When a client endorses a critical item:

  1. Review immediately - Don't wait until the end of the session
  2. Follow up directly - Ask open-ended questions about the endorsed item
  3. Assess thoroughly - Conduct a structured risk assessment if indicated
  4. Document your response - Record your clinical assessment and actions taken
  5. Take appropriate action - Safety planning, increased monitoring, or referral
  6. Notify if required - Supervisor, GP, or emergency contacts as appropriate
Clinical Obligation

A score of 1 or higher on PHQ-9 item 9 requires direct conversation about suicidal ideation, regardless of total score. Document your assessment and clinical response.


Understanding Change Over Time​

Types of Change​

When comparing assessment results over time, consider three types of change:

Change TypeDefinition
Raw changeSimple difference between scores (may be measurement error)
Reliable changeChange that exceeds measurement error
Clinically significant changeReliable change that crosses a clinical threshold

Reliable Change Index (RCI)​

Not all score changes are meaningful. The Reliable Change Index determines whether change exceeds what could occur by measurement error alone.

RCI thresholds for core assessments:

AssessmentRCI ThresholdInterpretation
PHQ-96 pointsChange of 6+ points is reliable at 95% confidence
GAD-75 pointsChange of 5+ points is reliable at 95% confidence
DASS-217 points (per subscale)Change of 7+ points is reliable at 95% confidence
K105.5 pointsChange of 5.5+ points is reliable at 95% confidence

Example: A client's PHQ-9 drops from 18 to 14. The raw change is 4 points, but this does NOT exceed the RCI threshold of 6. We cannot conclude this represents true improvement rather than measurement variability.

Duration-Adjusted Reliable Change (DARCI)​

Standard RCI uses the same threshold regardless of how much time has passed between administrations. Praxi also calculates the Duration-Adjusted Reliable Change Index (DARCI), which adjusts the threshold based on the interval between assessments.

Two modes:

ModeWhen to useHow it adjusts
Treatment monitoringDuring active treatmentStricter thresholds for short intervals (less change is expected early on)
Relapse preventionDuring maintenance or after dischargeMore sensitive for long intervals (any change during stable periods is noteworthy)

DARCI is shown alongside standard RCI in assessment results when two or more administrations are available. You do not need to configure it -- Praxi calculates both automatically.

Clinically Significant Change​

Two criteria must be met for change to be clinically significant:

  1. Reliable change - The change exceeds the RCI threshold
  2. Threshold crossed - The client has moved from clinical to non-clinical range (or vice versa)

Clinical thresholds:

AssessmentClinical thresholdMeaning
PHQ-910Score < 10 = non-clinical; Score 10+ = clinical
GAD-710Score < 10 = non-clinical; Score 10+ = clinical
DASS-21 Depression14Score < 14 = normal/mild; Score 14+ = moderate+
DASS-21 Anxiety10Score < 10 = normal/mild; Score 10+ = moderate+
DASS-21 Stress19Score < 19 = normal/mild; Score 19+ = moderate+
K1020Score < 20 = low; Score 20+ = elevated

Outcome Categories​

Based on reliable change and threshold crossing:

OutcomeDescriptionExample (PHQ-9)
RecoveredReliable improvement AND now below clinical threshold18 → 8 (change = 10, now below 10)
ImprovedReliable improvement but still above clinical threshold22 → 14 (change = 8, still above 10)
UnchangedChange within measurement error16 → 14 (change = 2, below RCI of 6)
DeterioratedReliable increase in symptoms12 → 19 (change = 7, above RCI of 6)
  1. Open the client's Assessments tab
  2. Select the assessment type (e.g., PHQ-9)
  3. View the score graph showing all administrations
  4. Hover over data points for detailed results
  5. Look for trend arrows and RCI indicators

Subscale Analysis​

When to Use Subscales​

Subscales provide more specific information about symptom patterns. Use subscale analysis to:

  • Differentiate between symptom domains
  • Target treatment to specific problem areas
  • Identify mixed presentations
  • Track domain-specific change

DASS-21 Subscale Interpretation​

The DASS-21 measures three distinct but related constructs:

SubscaleWhat it measuresHigh scores indicate
DepressionDysphoria, hopelessness, anhedonia, lack of interest, self-deprecation, inertiaLow mood, loss of pleasure, negative self-view
AnxietyAutonomic arousal, situational anxiety, subjective anxious affectPhysical anxiety symptoms, worry, panic
StressDifficulty relaxing, nervous arousal, irritability, over-reactivityTension, agitation, impatience

Interpreting profiles:

ProfileDescriptionClinical approach
Single elevated subscaleOne domain significantly elevatedTarget treatment to that domain
Multiple elevatedTwo or more domains elevatedBroader treatment approach; consider comorbidity
Mixed profileDepression and anxiety both elevatedCommon; may indicate mixed anxiety-depressive features
Discrepant subscalesLarge differences between subscalesUnusual presentation; explore further

PCL-5 Subscale Analysis​

The PCL-5 (PTSD Checklist for DSM-5) has four symptom clusters:

ClusterItemsFocus
Intrusion1-5Re-experiencing symptoms
Avoidance6-7Avoiding trauma-related stimuli
Cognition/Mood8-14Negative thoughts and feelings
Arousal15-20Hypervigilance and reactivity

Normative Comparisons​

Understanding Percentiles​

Percentiles compare your client's score to a reference population:

PercentileInterpretation
< 25thBelow average symptom levels
25th-75thAverage range
75th-90thAbove average symptom levels
> 90thSignificantly elevated compared to population

Australian Normative Data​

Praxi includes Australian normative data where available:

AssessmentAustralian norms sourceSample
DASS-21Lovibond & Lovibond (1995); Crawford & Henry (2003)Australian community
K10Slade et al. (2011); Australian National Survey of Mental Health8,841 Australian adults
PHQ-9Stocker et al. (2021)13,829 Australian adults
GAD-7Stocker et al. (2021)13,829 Australian adults

Selecting Appropriate Norms​

Consider the following when interpreting normative comparisons:

  • Age: Norms may vary by age group
  • Gender: Some assessments have gender-specific norms
  • Population: Community norms differ from clinical norms
  • Cultural background: Standard norms may have limitations for diverse populations

Cultural Considerations​

Validity Across Cultures​

Be aware of potential limitations when using standardised assessments with culturally diverse clients:

FactorConsideration
LanguageIs the translation validated? Does the client fully understand questions?
Concept understandingDo symptoms translate culturally? (e.g., somatic vs. psychological expression)
Response styleSome cultures may minimise or maximise symptom reporting
StigmaMental health stigma may affect disclosure
Normative dataAustralian norms may not apply to all cultural groups

Clinical Judgment​

Scores should be interpreted with awareness of:

  • Cultural background and worldview
  • Immigration and refugee experiences
  • Language proficiency
  • Community context and support
  • Cultural expressions of distress
Clinical Guidance

Assessment scores are one data point. Always integrate scores with your clinical interview, behavioural observations, and cultural understanding. When in doubt, discuss score interpretation collaboratively with the client.


Communicating Results​

To Clients​

Effective feedback involves:

  1. Explain the measure - What it assesses and why it's useful
  2. Share the score - Give the concrete number
  3. Contextualise - Explain what the score means
  4. Compare - Reference previous scores if available
  5. Discuss implications - What this means for treatment
  6. Invite questions - Ensure collaborative understanding

Example script:

"This questionnaire measures depression symptoms over the past two weeks. Your score was 14, which falls in the moderate range. This suggests you're experiencing significant symptoms that are likely affecting your daily life. Last time we did this, your score was 18, so we've seen a meaningful improvement of 4 points. This tells me the approach we're taking is helping, though there's still room to continue working on things. What's your sense of how things have been?"

To Referrers (GP Letters)​

When reporting to GPs, include:

ElementExample
Assessment name and datePHQ-9 administered 15 January 2026
Score and severityScore: 14 (Moderate)
Change from previousReduced from 18 (6 weeks prior)
Clinical interpretationReliable improvement but remains in clinical range
Treatment implicationsContinuing current treatment approach

Example GP letter excerpt:

"Outcome measurement using the PHQ-9 shows a reduction from 18 (moderately severe) to 14 (moderate) over the past 6 weeks. This 4-point reduction approaches the threshold for reliable change, suggesting treatment is having a positive effect. [Client name] remains in the clinical range and we will continue with the current treatment plan."

In Clinical Notes​

Document:

  1. Which assessment was administered
  2. Total score and severity classification
  3. Relevant subscales (if applicable)
  4. Any critical items endorsed and your response
  5. Comparison to previous scores
  6. Clinical interpretation
  7. Treatment implications

Red Flags and Patterns​

Scores Requiring Attention​

PatternConcernAction
Critical item endorsedImmediate safety concernAssess risk; document response
Sudden large increaseDeterioration or crisisReview treatment; increase contact
Maximum or near-maximum scoresSevere distressIntensive support; consider psychiatry referral
Inconsistent respondingValidity concernDiscuss with client; consider re-administration
Very rapid completionMay not have read items carefullyDiscuss; re-administer if needed
All items same responseResponse pattern suggests invalidityExplore engagement; discuss barriers

Automatic Validity Detection​

Praxi automatically flags two common validity concerns:

FlagWhat it detectsDefault threshold
Rapid respondingMedian response time below a minimum thresholdLess than 2 seconds per item
Straight-liningMost Likert-scale responses are the same valueMore than 80% identical responses

When either flag is raised:

  • The assessment results are marked with a validity warning
  • You can review the flags in the session results
  • If clinically appropriate, you can dismiss the flags by adding a clinical note explaining your reasoning
Dismissing Validity Flags

Some clients may legitimately complete assessments quickly (for example, because they are familiar with the items from previous administrations). Dismissing a flag records your clinical judgment and removes the warning from the results display.

Other Validity Concerns​

Additional signs an assessment may not be valid:

  • Contradictory responses (e.g., "not at all" for both sleep problems and sleeping too much)
  • Score dramatically inconsistent with presentation
  • Language or comprehension barriers evident

Assessment Summary​

On a completed assessment's results, Assessment summary asks Praxi for a summary of the result. It shows the total score, the instrument's published score band and the instrument's citation. It is worked out from the published scoring rules, not by an AI model, and it does not interpret the result for the client. If an instrument has no verified published band, the summary shows the score and says so. Interpretation stays with you.


Using Results Clinically​

Treatment Planning​

Assessment data informs treatment decisions:

DecisionHow assessments help
Diagnosis supportScreening tool results support (but don't replace) clinical diagnosis
Treatment intensitySeverity scores guide whether intensive or less intensive treatment
Focus areasSubscales and elevated items identify treatment targets
Progress monitoringRegular assessment tracks treatment response
Treatment endingDocument improvement to support discharge decisions

Session Integration​

Use assessment results in sessions:

  1. Before session: Review recent scores; identify discussion points
  2. Start of session: Share results briefly; get client's reaction
  3. During session: Explore elevated items; discuss changes
  4. End of session: Note implications for treatment plan
  5. Treatment review: Summarise trajectory; adjust approach if needed

Treatment Adjustment Based on Trajectory​

PatternConsider
Steady improvementContinue current approach; may reduce frequency
Plateau (no change)Adjust treatment strategy; add new interventions
DeteriorationReview formulation; intensify treatment; consider referral
FluctuationIdentify triggers; focus on stabilisation

Generating Reports​

PDF Progress Report​

Generate a professional PDF report showing a client's assessment progress over time:

  1. Go to the client's Assessments tab
  2. Click Download PDF
  3. Praxi generates a PDF including:
    • Client name, date of birth, and treatment period
    • Score trends for each assessment type administered
    • Baseline versus current scores with severity interpretation
    • Reliable Change Index (RCI) analysis for each comparison
    • Population percentile comparisons (where Australian norms are available)
    • Practitioner name, AHPRA number, and practice name

The report downloads as an A4 PDF suitable for sharing with GPs, insurance providers, NDIS plan managers, or the client themselves.

Practice Letterhead

If your practice has uploaded a logo in Settings > Branding, the PDF report will include your practice letterhead automatically.

Reports for Referrers​

When writing to GPs or other referrers, you can attach the PDF progress report to your correspondence. The report provides a clear, professional summary of treatment outcomes without requiring the referrer to access Praxi.


Best Practices​

Interpretation Guidelines​

  1. Context is key - Scores are one data point among clinical interview, observation, and history
  2. Use clinical judgment - Integrate assessment data with your overall formulation
  3. Pattern over point - Trajectory matters more than any single score
  4. Cultural awareness - Consider validity for client's background
  5. Client collaboration - Discuss scores and interpretation together

Documentation Standards​

  1. Record all administrations - Complete data enables tracking
  2. Note interpretation - Document clinical meaning, not just numbers
  3. Document critical item response - Record your assessment and actions
  4. Link to treatment - Connect findings to treatment plan
  5. Track consistently - Use the same measures over time

AHPRA and Medicare Compliance​

  • Use validated outcome measures appropriate to the client and presentation
  • Document assessment results and clinical interpretation in notes
  • Include outcome data in reports to GPs
  • Maintain assessment records for 7 years under the Privacy Act 1988
