ObjectiveFear of cancer recurrence (FCR) is reported by both cancer survivors and caregivers however less is known about caregiver FCR. This study aimed to (a) conduct a meta‐analysis to compare survivor and caregiver FCR levels; (b) examine the relationship between caregiver FCR and depression, and anxiety; (c) evaluate psychometric properties of caregiver FCR measures.MethodsCINAHL, Embase, PsychINFO and PubMed were searched for quantitative research examining caregiver FCR. Eligibility criteria included caregivers caring for a survivor with any type of cancer, reporting on caregiver FCR and/or measurement, published in English‐language, peer‐review journals between 1997 and November 2022. The COnsensus‐based Standards for the selection of health status Measurement INstruments (COSMIN) taxonomy was used to evaluate content and psychometric properties. The review was pre‐registered (PROSPERO ID: CRD42020201906).ResultsOf 4297 records screened, 45 met criteria for inclusion. Meta‐analysis revealed that caregivers reported FCR levels as high as FCR amongst survivors, with around 48% of caregivers reporting clinically significant FCR levels. There was a strong correlation between anxiety and depression and medium correlation with survivor FCR. Twelve different instruments were used to measure caregiver FCR. Assessments using the COSMIN taxonomy revealed few instruments had undergone appropriate development and psychometric testing. Only one instrument met 50% or more of the criteria, indicating substantial development or validation components were missing in most.ConclusionsResults suggest FCR is as often a problem for caregivers as it is for survivors. As in survivors, caregiver FCR is associated with more severe depression and anxiety. Caregiver FCR measurement has predominately relied on survivor conceptualisations and unvalidated measures. More caregiver‐specific research is urgently needed.

Objective Fear of cancer recurrence (FCR) is one of the most common unmet needs for cancer patients and caregivers. Yet little is known about the potentially unique nature of caregiver FCR. Our research aimed to address this gap by qualitatively exploring the features and impact of caregiver FCR. Methods Eighteen semi‐structured telephone interviews with cancer caregivers were conducted to explore the content and impact of caregiver fears and worries about cancer recurrence or progression. Data analysis used a Framework Approach. Results Qualitative analysis identified three themes (1) fear of the patient suffering, (2) the need to protect the patient from a recurrence and/or cancer‐related distress, and (3) caregiver's sense of unpreparedness and uncertainty. Underpinning these themes was an overarching sense of personal responsibility for the life of the patient. This overarching theme was identified as a key driver of caregivers' personal and patient‐centred fears. Conclusions Our findings confirm the conceptual differences between patient and caregiver FCR. Future research must therefore acknowledge the unique experiences of caregivers and prioritise the development of empirically driven theoretical models, instruments, and interventions for caregiver FCR.

2000. Spatial and temporal trends in soil properties at a soil quality benchmark site in central Nova Scotia. Can. J. Soil Sci. 80: 567-575. In response to concerns over the widespread soil degradation occurring on Canada's agricultural lands, Agriculture and Agri-Food Canada established a network of benchmark sites to assess soil quality change by monitoring agronomically important soil properties. The Nova Scotia site was established in 1989 on Queens (Gleyed Brunisolic Gray Luvisols) and Debert (Gleyed Dystric Brunisols) soil series under a corn-forage rotation within the Annapolis-Minas Lowlands ecoregion. The objectives of the project were to quantify temporal changes in agronomically important soil properties and determine how the property values vary with the landscape and components of the soil map unit. A 20 × 25 m grid was used in 1990 and again in 1995 to sample soil from the Ap horizon and to locate saturated hydraulic conductivity and penetration resistance measurements. The samples were analyzed for pH, organic C, total N, and available P and K. The results indicate that over 5 yr, organic C, C:N ratio, available P, and saturated hydraulic conductivity declined by 7.9, 4.7, 12.5, and 53%, respectively. Significant differences in pH, organic C, total N, available K, penetration resistance and saturated hydraulic conductivity were associated with selected components of the soil map unit. Slope position had a minimal effect on soil properties except for available K where the highest levels were located on middle slope positions. Interactions between particle size and slope position were found, with soils with coarse-loamy sola on upper slope positions having the lowest pH. The results of this study also demonstrated the utility of the method for monitoring soil quality change and the importance of the soil map unit in interpreting the spatial and temporal differences in soil properties.

Répondant aux inquiétudes relatives à la détérioration généralisée des sols agricoles du Canada, le ministère fédéral de l'Agriculture et de l'Agroalimentaire a implanté un réseau de sites repères pour évaluer les changements de qualité des sols en en surveillant en permanence les propriétés agronomiques. L'emplacement situé en Nouvelle-Écosse était installé en 1989 dans des sols des séries Queens (gluvisol gris brunisolique glyifié), et Debert (brunisol distrique, glyifié) sous rotation maïs-culture four-ragère. L'objet de l'étude était de quantifier l'évolution temporelle des propriétés agronomiques et de déterminer le degré de variation des valeurs mesurées par rapport au paysage et aux composantes de l'unité cartographique des sols. Une grille de 20 × 25 m était utilisée en 1990, puis en 1995, pour prélever des échantillons dans l'horizon Ap et pour situer les mesures de la conductivité hydraulique à saturation et de la résistance à la pénétration. L'analyse des échantillons portait sur le pH, sur...
